摘要/Abstract

Abstract: Asensitive polarographic catalytic wave system (Pb-0.24M HCl-0.6% NaAc-0.4% KI-0.4% ascorbic acid) for determining traces of lead in crops was proposed. The peak potential is-0.34V (vs. S. C. E.). The wave for the determination of lead within the range of 0—30μg/25ml is available. The detection limit of Pb is 0.002μg/ml. Eighteen metal ions and acid radicals are not interferential. The waves are clear and steady. The recovery is 92.6—107% and the variation coefficient is less than 3.41%.

Key words: Oscillopolarographic wave, Lead, Crops
