摘　　要：本文建立了电感耦合等离子体发射光谱(ICP-AES)同时测定玩具中8种可迁移元素含量的方法。此方法简便、快捷、高效,可实现多种元素同时测量。铅、镉、铬、钡、砷、硒、锑的线性范围为0.05~10.0 mg/L,汞的线性范围为0.02~0.5 mg/L,线性相关系数r>0.999。方法检出限在1.34~2.41 mg/kg,重复测量的相对标准偏差均小于5.19%,回收率为98.1%~108.4%,可以很好的满足测定要求。An inductively coupled plasma emission spectrometry(ICP-AES)method was developed for the simultaneous determination of 8 transferable elements in toys.This method is simple,fast and efficient,and can realize the simultaneous measurement of multiple elements.The linear range of lead,cadmium,chromium,barium,arsenic,selenium and antimony is 0.05~10.0 mg/L,and the linear range of mercury is 0.02~0.5 mg/L,with the linear correlation coefficient r>0.999.The detection limits were 1.34~2.41 mg/kg,the relative standard deviations of repeated measurements were less than 5.19%,and the recoveries were 98.1~108.4%,which can meet the determination requirements well.
