Application of Electro Analytical in Trace Metals Determinations: Environmental and Industrial Samples

Determination of the trace elements in both environmental and industrial sample are of great importance and attractive field for many researchers and scientists, and of high economic and environmental impact.Electro analytical methods show a remarkable sensitivity, broad scope and very low quantitation limit.A review of the modern electro analytical techniques, namely, cyclic, linear sweep, square wave and stripping voltametric techniques, in the trace metals determinations is highlighted.This review focus on the environmental and industrial applications used for each mode of electro analytical techniques.
