摘　　要：建立了一种检测彩泥中17种可迁移元素(砷、钡、镉、铬、铅、硒、铝、钴、铜、锰、镍、锶、锌、镓、铟、铊与铁)的电感耦合等离子体发射光谱(ICP-OES)法,方法检出限为0.25 mg·kg^(-1)～1mg·kg^(-1),相对标准偏差为1.09%～3.97%;测定彩泥中17种可迁移元素含量,对检验结果进行不确定度评定。A method for simultaneously determination of 17 migratory elements in play clay or modulling clay,including As,Ba,Cd,Cr Pb,Se,Al,Co,Cu,Mn,Ni,Sr,Zn,Ga,In,Tl and Fe by ICP-OES was developed.The detection limits were in the range of 0.25^-1mg·kg^-1 with the relative standard deviations（RSDs）of 1.09%-3.97%.The method uncertainty was evaluated.
