Voltammetric Determination of Fenitrothion

The adsorptive stripping differential pulse voltammetric method was proposed for the determination of fenitrothion [O,O-dimethyl O-(4-nitro-m-tolyl)phosphorothioate]. The voltammetric response was evaluated in 0,04 mol super(-1) Britton-Robinson buffer with respect to the accumulation time and poten...

Summary:The adsorptive stripping differential pulse voltammetric method was proposed for the determination of fenitrothion [O,O-dimethyl O-(4-nitro-m-tolyl)phosphorothioate]. The voltammetric response was evaluated in 0,04 mol super(-1) Britton-Robinson buffer with respect to the accumulation time and potential, and concentration dependence. The relationship between peak current and fenitrothion concentration was linear within the range of 1x10 super(-8) - 1x10 super(-6) mol l super(-1). In spiked water the detection limit of fenitrothion, estimated from 3 times the standard deviation, was 36 ng l super(-1). Interference from some other organophosphorus insecticides on the determination of fenitrothion were studied.
