| 摘 要： | 目的 建立一种测定化妆品中铅的新方法。方法 样品消化后，用同位镀汞法在-1.2V条件下电解富集40s，铅在-0.20V处有一良好的溶出峰。结果 最低检出限为0.03μgPb^2 ，同一样品平行测定6次，均值3.574mg/kg，相对标准偏差4.1%。在样品中加入一定量铅Pb^2 进行测定。回收率90%-100.5%。结论 电位溶出法可应用于基层单位化妆品中铅的测定。

| Abstract: | Objective To establish a method for determination of lead in cosmetics. Methods Samples were digested. The lead content was detected by isochronous mercury-plating method with the condition of lead cation being enriched for 40 s at -1.20V(vs. SCE). Results The stripping potential peak of lead appeared at - 0. 20 V( vs. SCE) . The detection limit was 0.03 jug Pb. Six parallel determinations of a sample were done with the mean of 3.574mg/ kg and the relative standard deviation of 4. 1% . Recovery rates obtained by standard addition test ranged from 90% -100.5% . Conclusion The method is suitable for detecting lead in cosmetics. |
