Voltammetric reduction behaviour and analysis of dichlone.

The voltammetric reduction behaviour of Dichlone has been carried out by d.c.polarography, cyclic voltammetry (CV), a.c.polarography and differential pulse polarography (DPP) in methanolic Britton-Robinson buffer of pH ranging 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 1.0×10-5 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 Dichlone in grains, soils and water samples.
