电感耦合等离子体原子发射光谱法测定化妆品中砷、铅、汞

Determination of As,Pb and Hg in Cosmetics by Inductively Coupled Plasma Atomic Emission Spectrometry

本文采用五氧化二钒作催化剂 ,HNO3- H2 SO4 消解法对化妆品前处理后 ,用电感耦合等离子体发射光谱仪同时测定砷、铅、汞。方法简便、快速。回收率在 95 %— 10 3.5 %之间 ,相对标准偏差不大于 3%

Simultaneous determination of the harmful elements As,Pb and Hg in cosmetics by inductively coupled plasma atomic emission spectrometry(ICP\|AES) was studied.The sample was digested and dissolved by HNO 3\|H 2SO 4,and vanadium pentoxide was used as a catalyst.The method is simple and rapid with high precision and accuracy.The relative standard deviation is less than 3% and the recovery is in the range of 95%_103.5%.
