共沉淀分离富集-ICP-AES法测定铜灰渣中金、铂、钯

摘要

An analysis method for determination of gold, platinum and palladium in copper slag by inductively coupled plasma atomic emission spectrometry (ICP-AES) with tellurium co-precipitation separation and enrichment was developed. The factors affecting determination were investigated, and the optimal detection conditions were determined. The detection limits were 5.6 (Au) µg/L,8.2 (Pt) µg/L and 3.6 (Pd) µg/L, the recovery ratio was 93.2%~102%, the relative standard derivation (RSD) was 1.21%(Au)~3.45% (Pt). The determination results were in good agreement with fire assaying. The method was accurate, simple and fast, and easy to master.%建立了碲共沉淀分离富集、电感耦合等离子体原子发射光谱法(ICP-AES)测定铜灰渣样品中微量元素金、铂、钯的方法。研究了影响测量的各种因素，确定了最佳测定条件。方法的检出限为：Au 5.6µg/L、Pd 8.2µg/L、Pt 3.6µg/L，回收率93.2%~102%，相对标准偏差(RSD)为：1.21%(Au)~3.45%(Pd)，方法测定结果与火试金法一致。方法准确、简便快速，易于掌握。
