| 摘 要： | 采用高压溶样弹，将样品用于硝酸－过氧化氢或高氯酸－过氧化氢溶解后，用ＩＣＰ－ＡＥＳ法对汞砷铅连续测定。方法回收率分别为８６．０％、９６．２％、９９．８％，ＲＳＤ分别为３．１７％、２．５１％、２．０１％。与原子吸收汉比较，无显著差异。应用于市售化妆品检测，结果满意。

| Abstract: | It is reported in this paper that the harmful elements, e.g. Hg, As and Pb, in cosmetics can be determined simultaneously by ICP AES. The sample is digested and dissolved with HNO 3 H 2O 2 or HClO 4 H 2O 2 in a closed PTFE vessel under pressure. The recoveries for Hg, As and Pb of the method found are 86.0%, 96.2% and 99.8% with RSD 3.17%, 2.51% and 2.01% respectively. The results obtained check very well with those obtained by AAS method. The method has been applied to the analysis of commodity cosmetics with satisfactory results. |
