摘　　要：用硫脲作铜的掩蔽剂 ,在磷酸二氢钠的弱酸性介质中 ,同时掩蔽铁 ,以示波极谱法测定铜精矿中镉、锌的含量。测定结果与ICP光谱法的分析结果相符。对样品进行精密度检验 ,相对标准偏差 (RSD ,n =5 ) <5 %。In this paper a method for the determination of cadmium and zinc in the copper concentrate by oscillopolarography is presented under the presence of thiourea as masking agent and in weak acidic medium of NaH 2PO 4 The results are in agreement with those determined by ICP-AES and the RSD(n=5) is less than 5%
