摘　　要：取纺织品试样（4.000 0 g）用80 mL模拟酸性汗液处理,使游离重金属（包括铅、镉、砷、铜、钴、镍、铬及锑）提取进入溶液。用电感耦合等离子体原子发射光谱法（ICP-AES）按所选的优化条件对其含量进行测定,测得该方法的检出限（3S/N）值与火焰原子吸收光谱法的检出限值基本相同。按标准加入法作了回收试验,回收率结果在81.6%~98.2%之间,相应测定值的相对标准偏差（n=6）在1.24%~8.31%范围内。Textile sample（4.000 0 g） was treated with simulated sweat（80 mL） to extract free heavy metals（including Pb,Cd,As,Cu,Co,Ni,Cr and Sb） into the solution and their contents determined by the method of ICP-AES under the optimized conditions.Values of detection limit（3S/N） found for the 8 elements by the present method were nearly same as those found by FAAS.Tests for recovery were made by the standard addition method,giving results in the range of 81.6% to 98.2%,with values of RSD′s（n=6） ranged from 1.24% to 8.31%.
