摘要： 建立了同时测定化妆品中铬、锰、镍、铜、锌、砷、硒、镉、锑、锡、汞和铅12种元素含量的测定方法。样品经微波消解,采用电感耦合等离子体质谱法(ICP-MS)同时测定12种元素。结果表明,12种元素线性关系良好(r=0.999 6~1.000 0),方法检出限为0.04~0.43 mg·kg-1,重复性实验的相对标准偏差为1.17%~9.69%,回收率为82.9%~115.1%。该方法简便快速、准确性高、可靠性强,可较好的应用于化妆品的元素测定。

Abstract: A method for determination of 12 elements:chromium (Cr),manganese (Mn),nickel (Ni),copper (Cu),zinc (Zn),arsenic (As),selenium (Se),cadmium (Cd),stibium (Sb),stannum (Sn),mercury (Hg) and lead (Pb) in cosmetics simultaneously was established.After being pretreated with microwave digestion,the 12 elements in cosmetics were detected by inductively coupled plasma mass spectrometry (ICP-MS).Results indicated that the relationship between the responds and the mass concentration of 12 elements shows good linearity with the value of r between 0.999 6 and 1.000 0.The detection limits of the method are between 0.04 and 0.43 mg·kg-1,and the relative standard deviations (RSD) of the repeatability are between 1.17% and 9.69%.Spiked recoveries of 12 elements are between 82.9% and 115.1%.This method is fast,simple,accurate and reliable,which could be applied for element analysis in cosmetics.
