An ICP-AES method was established for the simultaneous determination of Hg and As in crude antimony trioxide. The samples with different grades were digested in hydrochloric acid-tartraic acid-potassium chloride using microwave process system. The method is applied to analyze crude antimony trioxide with RSD% of 0.87%-3.2% for Hg, 1.3%-2.9% for As, and recovery of 90%-107%
建立了电感耦合等离子体原子发射光谱法（ICP - AES）同时测定粗三氧化二锑中汞和砷的方法。采用微波消解系统，在盐酸 - 酒石酸 - 氯化钾体系中对不同品位的样品进行消解。该方法用于分析粗三氧化二锑，汞的相对标准偏差（RSD%）为0.87% - 3.2%，砷的相对标准偏差为1.3% - 2.9%，回收率为90% - 107%
