Abstract

Polarographic and Voltammetric Determination of Dithianon in Environmental Samples

The electrochemical reduction behaviour of Dithianon has been studied by cyclic voltammetry (CV) and differential pulse polarography (DPP) in methanolic Britton-Robinson buffer of pH 2.0-12.0. The nature of electrode process was studied, the number of electrons was evaluated and the reduction mechanism was proposed. Quantitive determination was carried out in the concentration range 1.5×10-5 M to 2.5×10-8 M using a DPP method with a lower detection limit of 2.0×10-8 M. The proposed method was successfully applied in the determination of Dithianon in grains, soils and water samples
