Abstract


Electrochemical reduction behaviour of Aldicarb Sulfone has been carried out, by employing d.c. polarography, cyclic voltammetry (CV) and differential pulse polarography (DPP) in the supporting electrolytes of the pH ranging from 2.0 to 12.0. Differential pulse polarography has been developed for the quantitative estimation of Aldicarb Sulfonein various environmental samples using standard addition method. The nature of electrode process was studied, the number of electrons was evaluated and the reduction mechanism was proposed. Kinetic parameters such as transfer coefficient, diffusion coefficient and heterogeneous forward rate constant are evaluated and reported. Quantitative determination was carried out in the concentration range 1.1510-5 M to 2.2010-8 M using a differential pulse polarographic method with a lower detection limit of 1.810-8 M.
