Abstract
Electrochemical analysis is a powerful analytical technique that is utility in Pharmaceutical industry, metal industry, and environmental applications. Electro analysis of high advantages due to high sensitivity, reduction in solvent and sample consumption, high-speed analysis, low operating cost and high scan rate in all cases. A review of the modern electro analytical techniques, namely, cyclic, linear sweep, square wave and stripping voltametric techniques, are reported. This review gives industrial, Pharmaceutical, and environmental applications used for each mode of electro analysis techniques. (269 references, from 1922-2013).
