| Abstract: | A method for the determination of trace impurity elements including Co、As、Mo、In、Sn、Sb、Cd、Ag、Pd、 Au in high purity aluminium by ICP-MS after matrix extraction and separation was established. Effects of the oper-ation parameters of ICP-MS, acidity and the amount of complexant on the determination results of impurities were in-vestigated. The recoveries of all these trace impurity elements are in the range of 77.6%～112.2%, the detection limit is in the range of 0.02～0.6 ng/mL, and the RSDs are between 1.6% and 7.2%. |
