Resumo: | A derivative spectrophotometric procedure was developed for the determination of zinc(II) ethylenebisdithiocarbamate, Zineb, after formation of its blue colored complex with sodium molybdate in acidic medium. The Beer's law is obeyed up to 40 µg mL-1of Zineb at 956 nm. The detection limit was 0.006 µg mL-1 for Zineb when S/N ratio is 3 taking into account various parameters, such as the effect of acid concentration. The interference of a large number of ions on the determination of Zineb was evaluated. Most of the alkaline metals and metal salts did not interfere. The procedure presented proper sensitivity and it was applied for determining Zineb in food stuffs and commercial samples of Dithane Z 78 and Hexathane 75% W.P.. Results were compared with earlier reported methods. Zineb was successfully determined without any interferences in the presence of other dithiocarbamates like ziram, thiram, ferbam etc. |
