Determination of paracetamol at the electrochemically reduced graphene oxide-metal nanocomposite modified pencil graphite (ERGO-MC-PGE) electrode using adsorptive stripping differential pulse voltammetryLeve, Zandile Dennis January 2020 (has links)
>Magister Scientiae - MSc / This project focuses on the development of simple, highly sensitive, accurate, and low cost electrochemical sensors based on the modification of pencil graphite electrodes by the electrochemical reduction of graphene oxide-metal salts as nanocomposites (ERGO-MC-PGE; MC = Sb or Au nanocomposite). The electrochemical sensors ERGO-Sb-PGE and ERGO-Au-PGE were used in the determination of paracetamol (PC) in pharmaceutical formulations using adsorptive stripping differential pulse voltammetry. The GO was prepared from graphite via a modified Hummers’ method and characterized by FTIR and Raman spectroscopy to confirm the presence of oxygen functional groups in the conjugated carbon-based structure whilst, changes in crystalline structure was observed after XRD analysis of graphite and GO. / 2023-10-07

Potentiometric Titration of Sulfate Using A Lead-Mercury Amalgam Indicator ElectrodeRobbins, Charles W. 01 May 1972 (has links)
A lead sensitive indicator electrode was constructed with a 70 percent lead and 30 percent mercury amalgam billet. Sulfate concentrations in pure solutions, natural waters, and soil saturation extracts were determined potentiometrically using the lead-mercury amalgam indicator electrode and a standard calomel reference electrode. Sulfate concentrations over the range 0.4 to 20 milliequivalents sulfate per liter were determined with an automatic titrator and compared to a turbidimetric method for accuracy and precision. The values obtained by the two methods from twelve saturation extracts and three subsurface drainage waters were not significantly different and the potentiometric method was generally more precise. The automatic sulfate titration method has the advantages of increased sensitivity and speed.

Using Electrochemical Method to Study the Interaction Between DNA and a compound Known to Have Anticancer Property.Kamasah, Alexander 17 December 2011 (has links) (PDF)
The interaction of 4-(1'-[8'-(1''-pyrenyl)naphthyl])-2,6-diaminopyridine bis-glycamide bishydrocholride known to have anticancer properties with deoxyribonucleic acid (DNA) had been studied on a modified gold electrode by self-assembled monolayer using cyclic voltammetry. K4Fe (CN)6 was used as a probe to obtain electrochemical information on the electrode surface.
A bare gold (Au) electrode was modified with cysteamine and our results showed no change in the limiting steady state current as compared to the bare Au electrode. There was a reduction in the steady state current after the modification of the gold electrode with DNA. Immobilization of the DNA modified gold electrode with the anticancer compound also revealed a further reduction in the steady state current. The reduction in the steady state current is attributed to the receptor and DNA forming a nonelectrochemical complex due to the intercalation of the receptor and DNA on the gold electrode surface.

Electrochemical Studies of The Interaction Between DNA and a Compound Having Anticancer Properties.Pouliwe, Antibe 17 August 2011 (has links) (PDF)
Electrochemical method has been used to study the interaction between DNA and the compound N-(3',6'-dihydroxy-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthen]-5-yl)-N'-(2-imidazoyl)urea having anticancer properties. A DNA modified nanometer-sized gold electrode was prepared by surface modification of a bare gold electrode using cysteamine. These electrodes have been characterized using electrochemical techniques and were used to study the interaction between DNA and the compound. Our results showed an increase in the adsorption peak current and a negative shift of E1/2 in the oxidation of ferrocyanide on cysteamine and DNA modified electrodes. For the interaction between the DNA and the compound having anticancer properties, a decrease in peak current of the oxidation of ferrocyanide was observed. The decrease in peak current is attributed to the shielding of the electroactive species by the compound intercalated to the DNA from reaching the electrode surface. Therefore, only few of the electroactive species are able to reach the electrode surface.
