CRISTIAN NEAMTU, BOGDAN TUTUNARU, ADRIANA SAMIDE, ALEXANDRU POPESCU REDUCING THE ECOTOXICITY OF PESTICIDE POLLUTED WATERS BY ELECTROCHEMICAL METHODS Electrochlorination constitutes an electrochemical approach for the treatment of pesticide-containing wastewaters. This study evaluated the electrochemical and thermal stability of four pesticides and the efficiency of electrochlorination to remove and detoxify the simulated polluted water with: Acetamiprid, Emamectin, Imidacloprid and Propineb. This study reports the experimental results obtained by cyclic voltammetry and electrolysis at constant current density in association with UV-Vis spectrophotometry. In saline waters this pesticides are electrochemical active and anodic peaks are registered in the corresponding voltammograms. After thermal combustion, in a gaseous nitrogen atmosphere, a residue ranging from 15 to 45 % is observed at 500 °C.
