Abstract
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
