Para a comprova??o desta, foi realizada uma s?rie de experimentos para determina??o de melhor volume para trtamento, assim modificando as c?lulas eletrocin?ticas utilizadas. Os experimentos foram realizados em c?lula com volumes internos diferentes, variando de 0.2 L, 1.5 L e 3.0 L, variando assim o volume para melhor comprotar as amostras, desta forma favorecendo a defini??o de uma c?lula com melhor rendimento para o experimental. Em ambos os experimentos desenvolvidos o solo foi contaminado com concentra??es diferentes de petr?leo bruto da forma??o Umburana, variando entre 500 mg/L a 2500 mg/L, desta maneira constituindo a matriz sedimentar carbon?fera contaminada. Para configura??o da amostra utilizou-se de uma quantidade de sedimento com peso variando entre 0,05 Kg, 0.8 Kg e 1,5 Kg de rocha sedimentar carbon?fera macerada, o processamento foi feito para que esta atigisse uma fra??o granulometrica de 35# (mesh) ou 0.5 mm. A s?rie de experimentos ser? discutida em tr?s grandes unidades; Experimentos preliminares, interm?diarios e finais nos quais se consolidou uma metodologia para o Remedia??o Eletrocin?tica de Solos (RES) com maior rendimento devido s interferencias construtivas da propria c?lula utliada. Os eletrodos utlizados para a remedia??o foram o ?nodo Dimensionalmente Estavel (DSA) de Rut?nio-Tit?nio-?xido (Ti/Ru0,34Ti0,66O2) e eltrodos de Gr?fite Carbono (gr?fite sp2) aplicando diferentes correntes eletricas. A elimina??o dos compostos org?nicos foi monitorada mediante Carbono Org?nico Total (COT), Potencial Zeta (?) e medidas espectrofotom?tricas (UV-Vis?vel). Tamb?m foram feitas medida de potencial Hidrog?nio-i?nico (pH), condutividade (S/cm), e volume de vaporiza??o do eletr?lito utilizado (Na2SO4). Os resultados indicaram descontamina??o do meio entre 50% a 80% com baixo custo de 0.04 Real/kWh, sendo um bom percentual para remo??o de derivados de petroleo em solo. Os testes duraram entre 72 h a 480 h e foi verificada a remo??o de poluentes org?nicos nos compartimento cat?dico e an?dico, e com provavel carga de metais pesado. O potencial zeta indicou que os compostos org?nicos s?o transportados devido aos fen?menos de eletromigra??o e eletro-osmose, e confirma que o tamanho das part?culas varia ao decorrer do tempo de descontamina??o, formando assim ?cluster? de part?culas eletricamente carregadas que em sua grande maioria det?m carga negativa. A eletr?lise dos eletr?litos favoreceu a forma??o de um gradiente de pH, formando assim uma frente ?cida/b?sica constatada por n?lise dos eletrolitos nos reserv?torios, esta permitindo um aumento na mobilidade dos contaminantes do solo para os reservatorios. O efluente residual contaminado com petr?leo, tamb?m foi tratado com ox?da??o an?dica utlizando de eletrodo de dimanete dopado com boro (DDB) e densidades de corrente de 20 e 60 mA/cm2, os n?veis finais de descontamina??o atingido pelo tratamento acoplado foram de 80% no residual do efluente, definindo um alto n?vel de descontamina??o. / This work was carried out with the purpose of observing the application of electrokinetic treatment and behavior of its phenomena (electrolysis, electro-osmosis, electromigration and electrophoresis) in the decontamination of carbonaceous soils contaminated by exogenous components. To test this, a series of experiments was performed to determine the best volume treatment thus modifying electrokinetic cells used. The experiments were performed in cells with different internal volumes ranging from 0.2 L, 1.5 L and 3.0 L, thus varying the volume to better comprotar samples thus favoring the development of a cell with better performance for the experiment. In both experiments developed soil was contaminated with different concentrations of crude oil from the formation Umburana ranging from 500 mg/L to 2500 mg/L, thus constituting the contaminated sediment coal matrix. For configuration of the sample used is an amount of sediment weighing between 0.05 kg, 0.8 kg and 1.5 kg of coal sedimentary rock macerated, processing was done so that is reached one granulometric fraction of 35 # (mesh ) or 0.5 mm. A series of experiments will be discussed in three main units; Preliminary experiments, intermediate and final in which consolidated a methodology for Electrokinetic Remediation of Soils (RES) with higher yield due to constructive interference of s own utliada cell. The utlizados electrodes for remediation were Dimensionally Stable Anode (DSA) of ruthenium-titanium-oxide (Ti/Ru0,34Ti0,66O2) and electrodes of graphite carbon (graphite sp2) applying different currents eletricas. The removal of organic compounds was monitored by Total Organic Carbon (TOC), Zeta potential (?) and spectrophotometric measurements (UV-Visible). They were also made Hydrogen ion-potential measurement (pH), conductivity (mS/cm) and the volume of vaporization of the electrolyte used (Na2SO4). The results indicated decontamination of the medium between 50% to 80% with low cost 0.04 Real/kWh, with a good percentage for removal of oil derivatives on the ground. The tests lasted between 72 h to 480 h and checked for removal of pollutants in the cathodic and anodic compartment, with possible load heavy metals. The zeta potential indicated that the organic compounds are transported due to electromigration and electro-osmosis phenomena, and confirms that the particle size varies during the decontamination time, thus forming "cluster" of electrically charged particles that mostly holds negative charge. Electrolysis of electrolyte favors the formation of a pH gradient, thus forming an acid/base face detected by analysis of the electrolyte in the reservoirs, it is enabling an increase in mobility of soil contaminants to the reservoirs. The residual effluent contaminated with oil, has also been treated with anodic oxidation utlizando of electrode the dimond doped with boron (DDB) and current densities of 20 and 60 mA/cm2, the final levels of decontamination achieved by coupled treatment were 80% in the residual effluent defining a high level of decontamination.
