BATCH AND BENCH-SCALE FIXED-BED COLUMN EVALUATIONS OF HEAVY METAL REMOVALS FROM AQUEOUS SOLUTIONS AND SYNTHETIC LANDFILL LEACHATE USING LOW-COST NATURAL ADSORBENTS

Li, Chenxi 01 February 2008 (has links)
In this project, three separate experiments were conducted to assess heavy metal removal from metal aqueous solutions and synthetic landfill leachate by adsorption using low-cost natural adsorbents. Fundamental batch investigations indicated that the 4.0-4.75 mm crushed mollusk shells and the Sphagnum peat moss were the best adsorbents for cadmium and nickel removal, respectively. Peat moss was also found to have the highest adsorption capacities for manganese and cobalt adsorption. The adsorption capacities of the peat moss and crushed mollusk shells used as natural adsorbents for the adsorption of cadmium and nickel from binary aqueous solutions in fixed-bed columns under continuous flow conditions were investigated. The life expectancy of each adsorbent in the fixed-bed columns was also assessed for different hydraulic loading rates. The flow rate of 1.5 mL/min (surface loading of 27.52 cm3/cm2•day) and bed depth of 15 cm were identified as the better operational conditions from the column testing. The results indicated that 47.9% and 42.7% cadmium and nickel removal efficiencies could obtained under these operational conditions, respectively. Finally, the peat moss and the crushed mollusk shells were packed in bench-scale down-flow fixed-bed columns to evaluate their adsorption capacities as natural low-cost adsorbents for the removal of heavy metals from aerated and non-aerated synthetic landfill leachate. The flow rate applied in this operation was 1.5 mL/min (surface loading of 27.52 cm3/cm2•day). Peat was found to have the best adsorption capacities in columns treating aerated synthetic leachate for cadmium (78.6%) and nickel (83.8%) removal efficiencies. / Thesis (Master, Civil Engineering) -- Queen's University, 2008-01-31 22:37:34.381

The impact of heavy metals on the aerobic biodegradation of 1,2-dichloroethane in soil.

Balgobind, Adhika. January 2009 (has links)
1,2-Dichloroethane (1,2-DCA), a short chain chlorinated aliphatic compound, is one of the most hazardous toxic pollutant of soil and groundwater, with an annual production in excess of 5.44 × 109 kg. The major concern over soil contamination with 1,2-DCA stems largely from health risks. Owing to their toxicity, persistence and potential for bioaccumulation, there is a growing interest in technologies for their removal. Many sites are, however, co-contaminated with a complex mixture of 1,2-DCA and heavy metal contaminants. Co-contaminated environments are considered difficult to remediate because of the mixed nature of the contaminants and the fact that the two components often must be treated differently. Therefore, the objective of this study was to evaluate the aerobic biodegradation of 1,2-DCA by autochthonous microorganisms in soil co-contaminated with 1,2-DCA and heavy metals, namely; arsenic (As3+), cadmium (Cd2+), mercury (Hg2+) and lead (Pb2+), via a direct and quantitative measurement of the inhibitory effects of heavy metals in a microcosm setting. Effects of various metal concentrations and their combinations were evaluated based on the following: (i) degradation rate constants; (ii) estimated minimal inhibitory concentrations (MICs) of metals; (iii) concentrations of heavy metals that caused biodegradation half-life doublings (HLDs); and (iv) heavy metal concentrations that caused a significant effect on biodegradation (> 10% increase in t½ of 1,2-DCA). The effects of biostimulation, bioaugmentation and the addition of treatment additives on the biodegradation process were evaluated. The presence of heavy metals was observed to have a negative impact on the biodegradation of 1,2-DCA in both clay and loam soil samples, with the toxic effect being more pronounced in loam soil for all heavy metal concentrations except for Hg2+, after 15 days. Heavy metal concentrations of 75 mg/kg As3+, 840 mg/kg Hg2+, and 420 mg/kg Pb2+, resulted in 34.24%, 40.64%, and 45.94% increases in the t½ of 1,2-DCA, respectively, in loam soil compared to clay soil. Moreover, the combination of four heavy metals in loam soil resulted in 6.26% less degradation of 1,2-DCA compared to clay soil, after 15 days. Generally, more than 127.5 mg/kg Cd2+, 840 mg/kg Hg2+ and 420 mg/kg of Pb2+ was able to cause a > 10% increase in the t½ of 1,2-DCA in clay soil, while less than 75 mg/kg was required for As3+. An increased reduction in 1,2-DCA degradation was observed with increasing concentration of the heavy metals. In clay soil, a dose-dependant relationship between k1 and metal ion concentrations in which k1 decreased with higher initial metal concentrations was observed for all the heavy metals tested except Hg2+. Ammonium nitrate-extractable fractions of bioavailable As3+ and Cd2+ concentrations varied greatly, with approximately < 2.73% and < 0.62% of the total metal added to the system being bioavailable, respectively. Although bioavailable heavy metal fractions were lower than the total metal concentration added to the system, indigenous microorganisms were sensitive to the heavy metals. Biostimulation, bioaugmentation and amendment with treatment additives were all effective in enhancing the biodegradation of 1,2-DCA in the co-contaminated soil. In particular, biostimulation with fertilizer, dual-bioaugmentation and amendment with CaCO3 were most efficient in enhancing 1,2-DCA degradation resulting in 41.93%, 59.95% and 51.32% increases in the degradation rate constant of 1,2-DCA in the As3+ co-contaminated soil, respectively, after 20 days. Among all the treatments, dualbioaugmentation produced the highest 1,2-DCA degrading population of up to 453.33 × 107 cfu/ml in the Cd2+ co-contaminated soil. On comparison of the As3+ and Cd2+ co-contaminated soil undergoing either biostimulation or dual-bioaugmentation, similarity in the denaturing gradient gel electrophoresis (DGGE) banding patterns was observed. However, the banding patterns for the different bioremediation options demonstrated a difference in bacterial diversity between the fertilized and dual-bioaugmented samples. DGGE profiles also indicate that while numerous bands were common in the fertilized co-contaminated soils, there were also changes in the presence and intensity of bands due to treatment and temporal effects. Dehydrogenase and urease activities provided a more accurate assessment of the negative impact of heavy metals on the indigenous soil microorganisms, resulting in up to 87.26% and 69.58% decreases in activities, respectively. In both the biostimulated and bioaugmented soil microcosms, dehydrogenase activity appeared biphasic with an initial decrease followed by an increase in the treated soils over time. Results from this study provide relevant information on some alterations that could be introduced to overcome a critical bottle-neck of the application of bioremediation technology. In conclusion, the bioremediation strategies adopted in this study may be used as a rational methodology for remediation of sites co-contaminated with 1,2-DCA and heavy metals, subject to a thorough understanding of the microbial ecology and physico-chemical parameters of the site. / Thesis (M.Sc.)-University of KwaZulu-Natal, 2009.

Graphene-modified pencil graphite bismuth-film electrodes for the determination of heavy metals in water samples using anodic stripping voltammetry

Pokpas, Keagan William January 2013 (has links)
>Magister Scientiae - MSc / Electrochemical platforms were developed based on pencil graphite electrodes (PGEs) modified with electrochemically deposited graphene (EG) sheets and Nafion-graphene (NG) nanocomposites in conjunction with an in situ plated bismuth-film (EG-PG-BiE and NG-PG-BiE). The EG- and NG-PG-BiEs were used as sensing platforms for determining Zn2+, Cd2+ and Pb2+ by square wave anodic stripping voltammetry (SWASV). EG sheets were deposited onto pencil graphite electrodes by cyclic voltammetric reduction from a graphene oxide (GO) solution, while a dip coating method was used to prepare the NG-PG-BiE. The GO and graphene, with flake thicknesses of 1.78 (2 sheets) and 2.10 nm (5 sheets) respectively, was characterized using FT-IR, HR-SEM, HR-TEM, AFM, XRD and Raman spectroscopy. Parameters influencing the electroanalytical response of the EG-PG-BiE and NG-PG-BiE such as, bismuth ion concentration, deposition potential, deposition time and rotation speed were investigated and optimized. The EG-PG-BiE gave well-defined, reproducible peaks with detection limits of 0.19 μg L-1, 0.09 μg L-1 and 0.12 μg L-1 for Zn2+, Cd2+ and Pb2+ respectively, at a deposition time of 120 seconds. The NG-PG-BiE showed similar detection limits of 0.167 μg L-1, 0.098 μg L-1 and 0.125 μg L-1 for Zn2+, Cd2+ and Pb2+ respectively. For real sample analysis, the enhanced voltammetric sensor proved to be suitable for the detection and quantitation of heavy metals below the US EPA prescribed drinking water standards of 5 mg L-1, 5 μg L-1 and 15 μg L-1 for Zn2+, Cd2+ and Pb2+ respectively.

Okrajové hudební subkultury a s nimi spojená estetika jako výchozí bod pro tvorbu autorského představení / MARGINAL MUSIC SUBCULTURES AND EASTHETIC CONNECTED WITH THEM AS A STARTING POINT OF THE AUTHOR'S PERFORMANCE.

Burdová, Barbora January 2015 (has links)
The whole thesis has been trying to have a look into marginal music subcultures as a field of inspiration necessary with forming an author´s performance. One of the main sources of that is the metal sub-culture which is divided into other sub-sub-fields. Author is fixing the blackmetal sub-culture into center of attention and she is trying to undercover its possibilities by theatrical items. She is trying to look at common values between theater and metal music and she is interested in how to utilize music itself, which actually serves as sound curtain only. During authors creation she is interested into expression means replacing the text. Into the front position metal aesthetic is posted, as an outlet of scenographic way of thinking and creating, and last but not least, it is the main concern of interpretation of Sami´s culture and its transformation into theatrical form.

Thus, the aim of this study was to evaluate the effects of mycorrhizal inoculation in the development of Mimosa caesalpiniaefolia Benth. in soils manganese mining impact. The study was conducted in a greenhouse with experimental design of randomized type in a factorial arrangement 2x2x4, considering: two types of soil (degraded by tailings from the mining Mn and preserved forest); two soil conditions (sterile and natural) and four inoculation treatments (uninoculated (control), inoculated with G. clarum; inoculated with G. etunicatum; inoculated with G. clarum + G. etunicatum (Mix)), with four repetitions. At 60 days after transplanting were evaluated parameters: plant height, stem diameter, number of leaflets, dry matter of shoot and root, length of root system, relative chlorophyll index, spore density of AMF in the soil, root mycorrhizal colonization, mycorrhizal efficiency, macro accumulation (N, P and K) in shoots and manganese in shoot and root and translocation factor. The cultivation on degraded soil by waste of manganese mining reduced the development of thrush plants when compared to cultivated preserved in forest soil, regardless of soil condition and inoculation treatments. Inoculation with G. etunicatum and the Mix, favored the development of plants in sterile condition, regardless of the type of soil, increasing its capacity of tolerance to Mn. The high Mn content in the roots indicate that the thrush (Mimosa caesalpiniaefolia Benth.) May be effective in phytostabilization process in areas degraded by mining Mn. / A exploração mineral é considerada uma das principais ações antrópicas que causam a poluição do solo com metais, dentre os quais se encontra o manganês, que quando em excesso pode causar sintomas de toxidez, inibir o crescimento das plantas e causar alterações nas comunidades vegetais.

In and out of control : the consumption of loudness in the metal community / Contrôle et laisser-aller : consommation des volumes sonores extrêmes dans la communauté métal

Chauvin, Max 08 July 2014 (has links)
La consommation de musique live durant les concerts peut avoir des conséquences graves pour les individus et la société dans son ensemble. Cette thèse explore les motivations des consommateurs à s’exposer à des niveaux sonores extrêmes. Nous nous concentrons plus précisément sur le cas du métal, un genre qui place la puissance sonore au coeur de son identité collective. Nous analysons comment les amateurs du genre valorisent des niveaux sonores potentiellement délétères. Nous utilisons un paradigme sémiotique afin d’interpréter les données issues d’un travail ethnographique multi-méthodes et identifions quatre registres de valorisation : épistémique et transformatif, politique, spirituel, et esthétique. Cette approche dégage le sens profond et riche de la consommation de la puissance sonore et contribue ainsi à expliquer la résistance de certains consommateurs aux politiques de santé publiques promouvant la protection de soi. Notre analyse mitige également l’absolutisme des recommandations émises par la psychologie des comportements de santé du consommateur, un courant de recherche que nous analysons dans notre section théorique. / The consumption of live music during concerts can have dire consequences for individuals and society alike. This dissertation explores consumers’ motivations to expose themselves to extreme sound levels. Focusing on metal – i.e. a genre that places loudness at the heart of its collective identity – we discuss how music enthusiasts come to valorize potentially deleterious sonic stimuli. We use a semiotic framework to interpret our multi-method ethnography and identify four areas of valorization with respect to loudness: epistemic and self-transformative, political, spiritual, and aesthetic. This approach paints loudness consumption as a deeply meaningful process. In doing so, it helps to understand consumers’ resistances to the public policies that advocate self-protection from harmful sound levels. It also casts doubt about the absolutism that shrouds the recommendations issued from consumer health psychology, a research stream we review in our theoretical section.

In face of constant recollections and resignifications, in additional to several cases where history and memory of the present events are appropriated with political goals, we judge to be necessary understand how these events are represented, as these representations directly dialogue with the way the individuals and groups from the countries linked to these events comprehend them. Such study looks to comprehend hegemonies, resistances, revisionisms, relativizations and appropriations of history and memory, having music as the main source. This choice justifies itself in face of its power of communication because of its implicit lyrical and aesthetic discursive potential, further its reach both by its spread facilitated by the Internet and by the fact of Heavy Metal being one of the few musical genres with global reach.

A cena musical, mundialmente falando, a partir das d?cadas de 50 e 60, teve como um dos atores o jovem que foi mudando seu estilo, corpo de acordo com a moda influenciada pelos artistas nos filmes, nas revistas e nos programas de televis?o. Nesse sentido, este trabalho refere-se ao cen?rio em que Natal, no Rio Grande do Norte, foi influenciado atrav?s do rock, heavy metal e punk, construindo cenas que, de alguma maneira, uniram-se para a produ??o da m?sica. A juventude natalense, de alguma forma, teve a oportunidade de experienciar, nas d?cadas de 80 e 90, a m?sica pesada e criar para si espa?os de sociabilidade. A partir de um cen?rio pol?tico e econ?mico desfavor?vel ao crescimento, a cena heavy metal teve como ponto de encontro a loja de discos Whiplash onde jovens se aglomeravam para criar v?nculos e principalmente ouvir discos que eram tocados de dentro da loja. A partir dessa uni?o, formaram-se bandas e, com isso, puderam tocar em festivais e eventos na cidade com outros grupos de rock e punk. As informa??es que inicialmente circulam dentro das cenas chegavam por meio de fanzines. O fanzine foi o meio pelo qual se criou uma rede de amizades se espalhando pelo Brasil, em que a troca de informa??o e tamb?m de material fonogr?fico ajudava a minimizar o problema da crise financeira, al?m do fato de muitos destes jovens n?o terem trabalho para comprar seus bens de consumo. Estes fanzines funcionaram tamb?m para criar uma imprensa independente onde as bandas locais e eventos eram apresentados. / In Natal of the 80s, a musical scene was being created from the insertion of the young person in the spaces of the city like squares, disc stores, concerts, parks and etc. However, this music-related scenario underwent a process of transformation. The musical scene, worldwide speaking, from the 50s and 60s had as one of the actors the young man who was changing his style, body according to the fashion influenced by the artists in the movies, magazines, and television programs. In this sense, this work refers to the scenario in which Natal in Rio Grande do Norte was influenced through rock, heavy metal and punk, constructing scenes that somehow joined for the production of music. The natal youth somehow had the opportunity to experience heavy music in the 80's and 90's and create spaces for sociability. From a political and economic scenario unfavorable to growth, the heavy metal scene had as a meeting point the Whiplash record store where young people crowded together to create bonds and especially to listen to records that were played from inside the store. From this union, bands were formed and with that they could play in festivals and events in the city with other groups of rock and punk. The information that initially circulated within the scenes came through fanzines. The fanzine was the means by which a network of friendships was created spreading through Brazil where the exchange of information and also of phonographic material helped to minimize the problem of the financial crisis and the fact that many of these young people did not have work to buy their goods of consumption. These fanzines also worked to create an independent press where the local bands and events were presented.
