Abstract: The development of electrochemical methods for mineralization of agricultural organic pollutant imidacloprid in aquatic environment was investigated. In the present paper, the electrochemically generated strong oxidants destroy the pesticide in the bulk solution by oxidation reaction. The disappearance of pesticide as a function of time was estimated by differential pulse polarograph (DPP). As first, we have studied the electroanalytical behaviour of imidacloprid insecticide by DPP using a dropping mercury electrode (DME) as working electrode and Hg/Hg2Cl2, Cl-(sat) as a reference electrode in Britton-Robinson buffer (pH 3.0−10) as a supporting electrolyte.
