Abstract
Amperometric and coulometric methods of detection using glassy carbon electrodes, for liquid chromatographic determination of general thiuram disulfide, salts of alkyl-dithiocarbamates and alkylenbis-dithiocarbamates were evaluated.Several chromatographic methods for separation of these compounds were proposed based on a reverse-phase column including ion-suppression for N-alkyl-dithiocarbamates and methyl derivation for N-alkyl and alkylen-bisdithiocarbamates. The effects of several experimental parameters on the separation and the sensitivity of the methods were evaluated. Optimized methods were applied to determination of Thiram and Dimethyl ethylenebisdithiocarbamate in some fruits.
