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%.
