摘　　要：采用微波消解处理粉类、膏状类、溶液类化妆品,粉类等难消解样品加入适量HF溶液进行消解,电感耦合等离子体检测化妆品中的Sb,检测限为0.080 mg/kg,Sb质量浓度在0～100μg/L内线性良好,相关系数为0.9999,检测实际样品的回收率为82.3%～109%,RSD(n=10)为2.5%～6.5%。Different types of powder, cream, solution cosmetics were dissolved by using microwave digestion, and powder cosmetics which was undigestible were added proper amount of hydrofluoric acid. Detection of antimony in cosmetics using inductively coupled plasma mass spectrometry was little interference, low detection limit which was 0. 080 mg/kg for cosmetics. The linear range was wide over the concentration of 0 - 100 txg/L. Good correlation coefficient was 0. 9999. The recoveries were 82.3% - 109% , and the preeisions （n = 10） were 2.5% -6.5%.
