摘要
Abstract
A method for the determination of bismuth is reported with self _ made carbon paste electrode modified by cinchonine. After bismuth ions are accumulated under the applied potential of －1.00 V for 120 s on the chemical modified electrode in 1 mol/L H2SO4 solution, there is a sensitive oxidation peak of Bi at －0.022 V(vs SCE) in the determination by anodic stripping voltammetry(ASV). Dependence of current on concentration is linear from 1.0×10－8 to 1.0×10－4 mol/L of Bi3＋. The detection limit is 5.0×10－9 mol/L. Other metal ions do not interfere in the determination.关键词
