Abstract
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、县销售的99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禁用组分铅、砷、汞、镉、铬、钕、镍、铊、铍、锶和钴金属元素的含量情况.在质量浓度0~100μg/L(汞为0~5μg/L)时,仪器检出限为0.00060~0.05700μg/L,在定容体积25 mL、理论取样量为0.3 g时,方法检出限为0.000050~0.004800 mg/kg,线性相关系数均大于0.9966,加标回收率为78.2%~106.2%,相对标准偏差(RSD)小于5%.试验结果表明,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.
