摘要： 建立了电感耦合等离子体质谱法(ICP-MS)同时测定化妆品中铅、汞、砷和镉含量的方法。样品经密闭微波消解后,以铟作为内标物质,用ICP-MS同时测定铅、汞、砷和镉的含量,并将该方法和国家法定方法的检测结果进行比较。结果表明,4种元素标准曲线的线性关系良好,r值均为0.999 7,检出限为0.006～0.1 μg·L-1,重复性实验(n=6)的RSD为0.65%~4.82%,回收率为94.1%~108.6%。方法学比较表明该方法和国家法定方法的测定结果基本一致。

Abstract: A method for simultaneous determination of lead,mercury,arsenic and cadmium in cosmetics by inductively coupled plasma mass spectrometry (ICP-MS) was established.Indium was used as internal standard element.Samples were digested in a closed microwave oven.Contents of lead,mercury,arsenic and cadmium were simultaneously analyzed by ICP-MS,and the results were compared with that obtained from the national official method.The calibration curves for four elements showed good linearity with all correlative coefficients of 0.999 7;the limits of detection (LOD) were 0.006~0.1 μg·L-1;the relative standard deviations of repeatability experiments of samples (n=6) were between 0.65% and 4.82%;the spiked recoveries were between 94.1% and 108.6%.Methodological study showed that the results obtained from this method were basically consistent with that from the national official method.

Key words: cosmetics, heavy metal, microwave digestion, inductively coupled plasma mass spectrometry
