  • Abstract

    The electrochemical behavior of vinclozolin [3-(3,5-dichlorophenyl)-5-methyl-5-vinyl-1,3 oxazolidine-2,4-dion] in dimethylsulfoxide was performed by cyclic voltammetry (CV) and linear sweep voltammetry (LSV). The main decomposition pathway included in the cleavage of chlorine atoms at platinum electrode. The general reduction mechanism of this compound has been suggested based on the results obtained. The peak potential and peak current were found to be depending on pH of the buffer solution. The measuring system response was linear over the vinclozolin concentration range from 1.010-3 to 5.010-7 mol L-1 and the detection limit (LOD) achieved was 1.110-8 mol L-1 (2.5 μg L-1) at pH 4.0. Vinclozolin was determined in spiked serum sample.
