Abstract

In this approach electrode kinetics and mechanism of pesticides having different electro active centres at carbon nano tubes paste electrode was studied. Universal buffer used as supporting electrolyte and the techniques employed are cyclic voltammetry, differential pulse adsorptive stripping voltammetry, millicoulometry and controlled potential electrolysis. All investigations were made from pure samples dissolved in di methyl formamide. Peak currents were linear over the concentration range of 10-7 M to 10-12 M with lower detection limits of 1.02x 10-11 M. The relative standard deviation and correlation coefficients for phenothrin, chlorpropham and fenclorim are found to be are found to be 1.30%, 0.998, 1.25%, 0.996 and1.26%, 0.997respectively for 10 replicates.
