Determination of endosulfan by stripping voltammetry
Abstract
The electroreduction and adsorption of endosulfan was studied in aqueous and acetonitrile media. The optimum experimental conditions were derived at a stationary glassy carbon electrode by differential-pulse and square-wave stripping voltammetric techniques and used for the determination of endosulfan in soil samples. The best determination limit (ng ml–1 and lower) for endosulfan in a soil sample was obtained with the square-wave stripping technique in an aqueous acetonitrile medium.
