AbstractAbstract
[en] A measurement method for simultaneous determination of impurities (Cu, As, Se, Ag, Cd, Sn, Te, Pb, Bi) in high purity antimony by using inductively coupled plasma mass spectrometry (ICP-MS) was studied. The samples were dissolved by nitric acid, aqua regia solution, nitric acid and hidrochloric acid mixed bromic acid then were measured directly on ICP-MS.The effect of matrix element antiony was evaluated. The recoveries were 90%-98% when samples were treated by aqua regia solution and HNO3+HCl+HBr. The relative standard deviations were smaller than 10%. The procedure was applied to determination of impurities in high purity antimony higher than 99%, meets the requirements of some domestic antimony export enterprises. (author)
