摘　　要：建立了电感耦合等离子体质谱法(ICP-MS)测定儿童座椅中硼、铝、铬、锰、钴、镍、铜、锌、砷、硒、锶、镉、锡、锑、钡、汞、铅17种可迁移元素的方法。方法检出限为6~68μg/kg,加标回收率在90%~105%之间,相对标准偏差为1%~4%,方法满足EN71-3标准和GB 6675.4标准的检测要求,适合儿童座椅中可迁移元素的测定。A method for the determination of 17 elements（ Al,Sb,As,Ba,B,Cd,Cr,Co,Cu,Pb,Mn,Hg,Ni,Se,Sr,Sn,Zn） in child seats by ICP-MS was developed. The method detection limits were in the range of 6 ~ 68 μg/kg,the proposed method was applied to the analysis of child seats. The average recoveries of this method were in the range of 90% ~ 105%,and relative standard deviations（ RSDs） were between 1% ~4%. This method can meet the testing requirements in EN71-3 standard and GB 6675. 4 standard,it is suitable for the determination of migratory elements in child seats.
