【摘要】 采用高压溶样弹，将样品用硝酸－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。方法的回收率分别为８６．０％、９６．２％、９９．８％，变异系数分别为３．１７％、２．５１％、２．０１％。与原子吸收法比较，无显著差异。应用于市售化妆品检测，结果满意。更多还原

【Abstract】 Sample was digested in polytetrafluorethylene sealed vesssle by nitric acid-perhydrol or high chloric acid-perhydrol, Hg As Pb were simultaneously determinated by ICP-AES. The recoveries were 86.0%, 96.2%, 99.8% and the relative standard deviation were 3.17%, 2.51%, 2.01%. The results between AAS and ICP-AES has no significant difference.更多还原
