摘要：

依据微波消解-电感耦合等离子体质谱法（ICP-MS）对甘肃省27个市、州、县地区抽样的30批次唇膏类化妆品进行检验,采用在线内标校正,外标法定量分析唇膏类化妆品中金属元素的种类、含量情况。在曲线范围0~100 μg/L （Hg：0~5 μg/L）时,仪器检出限为0.000 11~1.6 μg/L,在定容体积25 mL,理论取样量为0.3 g时,方法检出限为0.000 009 2~0.13 mg/kg,线性相关系数均大于0.995 1,加标回收率为81.8%~120.0%,RSD小于5%。试验结果表明,该方法在同时测定唇膏中多种元素过程中,方法简便、快捷、省时、节约成本,并且灵敏度高、重现性好。

Abstract:

Thirty batches of lipsticks sampled from twenty-seven districts in Gansu province were tested by microwave digestion coupled with ICP-MS. The types and concentrations of metal elements in lipsticks were determined separately by online internal standard calibration and external standard method. The detection limit of the instruments was 0.000 11~1.6 μg/L in the range of 0~100 μg/L （Hg: 0~5 μg/L）. When the constant volume was 25 mL and the theoretical quantity of the sample was 0.3 g, the detection limit of the method was 0.000 009 2~0.13 mg/kg; the linear correlation coefficients were all greater than 0.995 1; the recoveries of spiked samples were 81.8%~120.0%; the relative standard deviations （RSD） were less than 5%. The test results showed that this method was simple, rapid, time-saving, cost-saving and accurate and had good reproducibility in the simultaneous analysis of various elements in lipsticks.
