摘要：

A very sensitive electrochemical stripping procedure for azinphos-methyl (Guthion) is reported. Accumulation is achieved by adsorption of the compound on a hanging mercury drop electrode. The adsorptive stripping response was evaluated with respect to accumulation time and potential, concentration dependence, electrolyte and other variables. The determination limit is 0.2 ng ml-1 after 300 s accumulation and 0.4 ng ml-1 after 180 s accumulation. The procedure was applied to spiked river water. © 1990.
