摘要：

The electrochemical reduction behavior of organophosphorous pesticides such as monocrotophos, phosphamidon, and dichlorvos have been studied bv employing dc polarography, cyclic voltammetry, ac polarography, differential pulse polarography, millicoulometry, and controlled potential electrolysis. The general reduction mechanism of these compounds has been suggested based on the results obtained. A differential pulse polarographic method is developed for the determination of title compounds in agricultural formulations. Both standard addition and calibration methods are used for the analysis experiments. The lower detection limits are found to be 1.0 x 10(-8), 1.25 x 10(-8) and 1.2 x 10(-8) respectively.
