摘要：
Malathion and dimethoate on alkaline hydrolysis with potassium hydroxide yield potassium dimethoxy dithiophosphate, which reacts at DME to give analytically useful and well-defined diffusion-controlled waves at peak potentials of -0.30 and -0.27 V respectively. This observation has made the basis of a differential pulse polarographic (DPP) method for the determination of above insecticides.
