摘　　要：采用微波消解技术对样品进行消解,用电感耦合等离子体光谱法测定化妆品中锑的含量。通过优化试验确定了仪器功率、观察高度、分析谱线等参数。锑含量在0~5 mg/L范围内与强度呈良好的线性关系,相关系数为0.9999,方法检出限为0.4μg/L,样品加标回收率为90%~97%,测定结果的相对标准偏差为0.7%（n=6）。The cosmetic samples were digested by microwave digestion technology.Stibium in cosmetics was determined by inductively coupled plasma emission method.The condition of instrument was optimized such as power,observation height,analytical line etc.The intensity was linear with the concentration of stibium in the range of 0-5 mg/L with the correlation coefficient of 0.999 9.The detection limit was 0.4 μg/L,and the recovery was 90%-97%.The RSD of determination results was 0.7%（n=6）.
