Özet:

 

This paper describes a sensitive and accurate adsorptive catalytic   stripping voltammetric method for the determination of zineb (zinc ethylene-bis-   dithiocarbamate) in tap water and tomato samples. The method is based on the   reduction of adsorbed zineb at a hanging mercury drop electrode following   its catalytic oxidation using peroxydisulfate as an oxidizing reagent.   Chemical and instrumental parameters of the process were optimized. The   catalytic mechanism of the reduction of zineb is discussed as well. The   limits of detection (3 s) and quantification (10 s) and linear range of the   method for accumulation time of 60 s were calculated as 8.1 nM, 28 nM, and   0.028--7.00 m M, respectively. The relative standard deviation of the   method was 3.68% for 2.5 m M zineb (N = 5). The proposed method was   applied successfully for the determination of zineb in tap water and tomato   samples.
