X射线荧光元素分析技术对化妆品中铅和砷快速检测的初步探讨

目的: 建立X射线荧光元素分析技术检测化妆品中的铅、砷。 方法: X射线荧光元素分析仪,测试时间180 s,标准偏差2 σ,采用模式:塑料模式。 结果: 铅元素浓度在9.93~100.10 mg·kg^-1之间,砷元素浓度在4.98~100.10 mg·kg^-1之间呈良好的线性关系。铅加样回收率为94.3%,砷加样回收率为97.6%。 结论: 本方法简便快速,适合化妆品中铅、砷的快速测定。

Objective: To establish a method for rapid determination of Pb and As elements in cosmetics by X-ray fluorescence elemental technology. Methods: X-ray fluorescence elemental analyzer was employed with the following settings,test time: 180 s,standard deviation: 2 σ,mode:plastic mode. Results: The linear ranges were 9.93-100.10 mg·kg^-1 for Pb,and 4.98-100.10 mg·kg^-1 for As.The average recovery of Pb was 93.7%,and that of As was 97.5%. Conclusion: The method is simple and rapid,which can be used for the rapid determination of Pb and As elements in cosmetics.
