Abstract

New procedures for the determination of pesticide carboxin were developed using differential pulse voltammetry, HPLC with amperometric detection and chronopotentiometry at carbon paste electrode and reticulated vitreous carbon electrode, respectively. Developed procedures based on electrochemical oxidation of carboxin were successfully applied on the determination of carboxin in the model samples of drinking and river water. Limits of detection in samples of river water were in 10-7molL-1 concentration range for all procedures and electrodes used. All developed procedures proved to be sensitive, accurate and, due to the resistance of the electrode to the passivation, also simple to handle.
