The commercial bupirimate pesticide (5-butyl-2-(ethylamino)-6-methyl-4-pyrimidinyl dimethyl sulfamate) is widely used for crop production and fruit tree treatment, but this disposal cause serious environmental problems. This work presents an electrochemical oxidative removal of this pesticide by an electrolysis system on a boron-doped diamond (BDD) anode and platinum cathode. A number of experiments were run and the results are presented. The achieved reductions were 74% and 52% for 2% NaCl and 3% NaCl respectively. The chemical oxygen demand (COD) of bupirimate solution was observed to fall with pseudo first-order kinetics. As a conclusion, electrochemical oxidation could be used as a pretreatment stage for detoxification of toxic wastes with bupirimate.
