摘要
研究了在盐酸体系中,采用微分脉冲极谱法测定湿法炼锌中间过程溶液中的锑。结果表明:在-0.13V左右,产生灵敏的微分脉冲极谱波;锑浓度在8×10-8～8×10-6 mol/L范围内与相应峰电流有良好的线性关系,检测限为4×10-8 mol/L。该方法灵敏、简单、快速,已成功用于湿法炼锌电解液中锑的测定。
In hydrochloric acid solution system, antimony in intermediate liq form a sensitive adsorptive complex wave at about -0.13 V by differential uid of zinc hydrometallurgy pulse polarography. There is a good linear relationship between the concentration and corresponding peak current. When the concentration of Sb is between 8 10^-8 -810^-6 mol/L, the detection limit is 4 10^-8 mol/L. The method ,which is sensitive, simple and rapid, has been successfully used to determine antimony in intermediate liquid of zinc hydrometallurgy.
