ICP-MS Determination of 15 Harmful Elements in Cosmetics
摘 要
试样在硝酸及极少量硫酸中,采用微波消解前处理,用电感耦合等离子体质谱法同时测定化妆品中铍、钒、铬、镍、砷、硒、锶、钼、钯、镉、钕、金、汞、铊、铅等15种有害元素,通过样品前处理和电感耦合质谱法测定时条件的选择并以内标法测定,消除了基体效应和干扰,各待测元素的检出限(3S)在0.004~0.139 mg·kg-1,仪器的精密度(n=6)在1.59%~9.88%之间,方法的精密度(n=6)在1.88%~4.86%,15种元素的加标回收率在84.32%~123.70%,样品溶液消解后,在冰箱0~5 ℃保存,2d内各元素稳定性良好.
Abstract
Samples of cosmetics were dissolved by digestion with HNO3 and a small amount of H2SO4 in the CEM Mars XP Microwave digester,and the solutions obtained after dilution to a definite volume were used for ICP-MS determination of Be,V,Cr,Ni,As,Se,Sr,Mo,Pd,Cd,Nd,Au,Hg,Tl and Pb.Analytical conditions of ICP-MS were optimized,and the internal standard method was used in quantification to afford elimination of matrix effect and interferences.Detection limits (3S) of the 15 elements determined were determined and calculated as defined by IUPAC,and the values obtained were in the range of 0.004 μg·L-1 to 0.139 μg·L-1.Precision of the instrument operated under the prescribed parameters,and of the method of sample analysis were tested,giving values of RSD′s (n=6) in the ranges of 1.59%-9.88% and 1.88%-4.86% respectively.Tests for recovery were made at 3 different concentration levels,giving values in the range of 84.32%-123.70%.Sample solutions were kept in refrigerator at 0-5 ℃ and were stable within 2 days.
