Abstract
The degradation of insecticide methidathion organophosphorous pesticide in aqueous medium has been studied by anodic oxidation using a boron-doped diamond (BDD) anode. The results obtained show that the application of electrolysis in pesticide allows to reduce the COD. For 2% NaCl and 3% NaCl the achieved reduction was 85% and 72% respectively. In all cases, the pH of electrolysis was significantly reduced after 45 min. The COD of methidathion solution was observed to fall with pseudo first-order kinetics. An increasing of applied current leads an increase of the rate of electrochemical oxidation process. The effect of temperature shown that for 25°C and 65°C the achieved reduction was 85% and 66% respectively. The activation energy indicate that the electrochemical degradation is complex.
