Fund Project: The authors gratefully acknowledge the financial support of this study by the National Natural Science Foundation of China (No. 20562009),the Jiangxi Province Natural Science Foundation (No. 0620041),the State Key Laboratories of Electroanalytical Chemistry of Changchun Applied Chemical Institute (No. SKLEAC2004-3) and Chemo/ Biosensing and Chemometrics of Hunan University (No. 2005-22).

The electrochemical behaviour and electrode reaction mechanism of ziram (zinc-dimethyl dithiocarbamate) on a hanging mercury drop electrode were investigated in Britton-Robinson (B-R) buffer by using cyclic and square wave voltammetry (SWV).Based on these studies a voltammetric method for determination of ziram was developed and applied to determine the ziram in synthetic and spiked vegetable samples,satisfactory results were obtained in both eases.
