In this research， ICP-AES was used for determining ten impurity elements (Fe， Pb， Ca， Mg， Cu， Zn， Al， As， Sb， and Bi) in tin concentrate and smelting products， such as crude tin and slag。 Samples were dissolved by hydrochloric acid and nitric acid。 Determination conditions were investigated in detail。 Influences of matrix and coexisting elements were eliminated by selecting proper analysis spectral lines。 Under the optimum conditions， the correlation coefficient of calibration curves were higher than 0。999。 The detection limits of these ten impurities were in the range between 0。0009 to 0。0621 μg/ml。 Relative standard deviation (RSD) values were lower than 6。0%， and the recoveries of standard addition were between 85 and 109%。 The proposed method was demonstrated to be reliable by comparing with standard analysis methods and certified values of standard sample。 It could be applied for determining impurity elements in tin concentrate and smelting products successfully。
