Recent developments in electrode materials and methods for pesticide analysis - An overview

Different types of electrode materials have been developed recently for the potential application in pesticide sensor analysis. These electrodes are employed for the determination of organophosphates, carbamates and methyl parathion. This short review article gives an overview of different analytical and electrochemical methods (High performance liquid chromatography, cyclic voltammetry, square wave voltammetry, differential pulse voltammetry and electron impedance spectroscopy) reported for the pesticide detection and new kinds of electrode materials including carbon nanomaterials, metal oxides, conducting polymers and clays based materials for the detection of environmentally and biologically toxic pesticides and herbicides. The recently developed electrode materials which are able to detect upto lower level concentrations of pesticides with high sensitivity and specificity have been reviewed. Real sample studies carried out in apple, cabbage, tap water and lake water were also overviewed.
