Electrochemical Degradation of the Pesticide Dimethenamid‐P at Gold,DSA Platinum and Ruthenium Oxide Electrodes in Different Electrolytes

For the first time the electrochemical degradation of the pesticide dimethenamid‐P was studied. Its direct electrochemical degradation, using potential cycling at a gold electrode, was performed by cyclic voltammetry and HPLC analysis of electrolyte after 72 h showed 56.8 % of degradation. HPLC‐MS indicates the formation of degradation products through the elimination of chlorine atom and C? N bond cleavage. By indirect electrolysis using DSA Ti/PtOx and DSA Ti/RuO₂ electrodes during 30 minutes 87.2 % and 88.3 % of dimethenamid‐P was degradated, respectively. The high percentage of degradation of dimethenamid‐P was achieved with non time consuming, simple and cheap electrochemical processes.
