摘要
在HCl-KCl底液中 ,Pb在峰电位 - 0 .5 5V(对氯化银电极 )处有一灵敏的溶出峰。本文详细探讨了溶出分析的最佳条件。本方法适用于钼精矿及氧化钼中Pb的测定 ,回收率为 96 %～ 10 3% ,相对标准偏差RSD为 1 6 4 %～ 2 70 %。
It was found that the senstitive stripping peak potentials of Pb was -0.55 V in a supporting electrolyte of HCl-KCl.The optimum conditions for the determination of Pb by differential potential stripping analysis have been studied.The method can apply to the determination of Pb in molybdenum products.Its relative standard deviation was 1.64%～2.70%,and the recovery was 96.0%～103.0%.
