Electrochemical oxidation of tannery wastewater

Journal of Chemical Technology & Biotechnology, 2001
AbstractTannery wastewater was treated by an electrochemical oxidation method using Ti/Pt, Ti/PbO2 and Ti/MnO2 anodes and a Ti cathode in a two‐electrode stirred batch reactor. The changes in colour concentration, chemical oxygen demand (COD), ammonia (NH4+), sulfide and total chromium have been determined as a function of treatment time and applied ...

Unusual electrochemical oxidation of cholesterol

Steroids, 2008
It has been found that cholesterol undergoes direct electrochemical oxidation on platinum electrode in dichloromethane. Voltammetric measurements show that the process is controlled by the rate of electron transfer and the height of the oxidation peak is linear vs. concentration of cholesterol.

Electrochemical oxidation of selenocystine and selenomethionine

Colloids and Surfaces B: Biointerfaces, 2009
Electrochemical oxidation of selenocystine (SeCys) and selenomethionine (SeMet), on a gold electrode was studied by cyclic voltammetry (CV), rotating disk electrode technique (RDE) and chronocoulometry (CC). In 0.2 mol/L HAc-NaAc (pH=3.90) supporting electrolyte, anodic peak I potential of SeCys and SeMet was 810 mV and 638 mV, respectively, and this ...

Electrochemically Induced Growth of Zinc Oxide

ChemPhysChem, 2007
AbstractThe electrolytically induced precipitation of zinc oxide from zinc nitrate solution on gold surfaces in the presence of water‐soluble polymers was examined for reaction times between 0.5 and 600 seconds. Regardless of the additive, polycrystalline films of zinc oxide have formed after 30 seconds, but polymeric additives dramatically change the ...

Electrochemical oxidation of zopiclone

Monatshefte für Chemie - Chemical Monthly, 2015
Electrochemical behaviour of zopiclone was investigated on glassy carbon electrode in static and rotation disc arrangement. Strong influence of kinetics and adsorption phenomena on the electrode processes was proved by voltammetric techniques. Controlled potential electrolysis in off-line and on-line combination with tandem mass spectrometry was ...

Effect of the electrochemical oxidation/reduction cycle on the electrochemical capacitance of graphite oxide

Carbon, 2014
Abstract Reduction largely affects the properties of graphene oxide (GO), because the content of each functional group changes by the oxidation degree. So far no study about re-oxidation and re-reduction of GO has been carried out. Herein, we report the effects of oxidation/reduction cycle of graphite oxide (GtO, multilayered GO) on its composition ...

Electrochemical Oxidation of Methane to Methylamine

Journal of the American Chemical Society
The electrochemical methane (CH4) oxidation reaction under ambient conditions is a promising approach for natural gas utilization. However, the highly stable nature of CH4 restrains efficient cleavage of the C-H bond without overoxidation. To this end, we proposed a coupled oxidative strategy for converting CH4 to value-added products via NH2 ...

Electrochemical oxidation of nitroylides

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1981
The mechanisms of the electrochemical oxidation of mono- and dinitroylides of S and Se on a Pt electrode in CH3CN have been studied for the first time. It was shown that the cation radical formed as intermediate was able to react with the medium with removal of an H atom and with the formation of an onium cation or to undergo decomposition.
