In this investigation a sensitive method for the determination of the herbicide fenclorim by adsorptive stripping voltammetry (AdSV) at carbon nano tubes paste electrodes (CNTPE) at pH 4.0 was described. The cyclic voltammograms demonstrate the adsorption of these compounds at the working electrode. A symmetric study of the various operational parameters such as Accumulation potential (-0.8V) and (60s) accumulation time that affect the stripping response was carried out by differential pulse voltammetry. Universal buffer with pH range 2.0-6.0 used as supporting electrolyte. The peak heights are in linear trend over the concentration range of 1.0 x 10 -8 to 1.0 x 10 -5 M. The relative standard deviation and correlation coefficient for fenclorim was 0.97% and 0.998 respectively. The lower detection limit for fenclorim was 0.92×10 -7 M. The degree of interference of some other pesticides on the differential pulse adsorptive stripping signal for fenclorim was evaluated. Finally the proposed method was applied for determination of fenclorim ingrains (wheat and rice) and water samples.
