| Abstract: | 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% |
