摘要
建立采用氢化物发生电感耦合等离子发射光谱（HGdCP-AES），测定纺织品中可萃取痕量汞的方法。通过对ICP—AES工作参数进行优化和选择，方法的检出限为0．11μg／L，最小检出量为0．0022mg／kg；汞含量为20．0μG/L时，相对标准偏差为4．9％；汞含量为5．5μg／L时，相对标准偏差为6.3％（n=8）；回收率为93．3％-102．7％。该方法可满足Oeko-Tex标准100对纺织品中可萃取痕量汞的检测要求。
A method for the determination of trace extractable mercury in textiles by HG-ICP-AES has been developed. Operation parameters of ICP-AES were optimized and selected. The detection limit was 0.11 μg/L. The minimum detection quantity was 0, 0022 mg/kg. The RSD was 4.9% at a level of 20.01μg/L and 6.3% for 5.51μg/L（ n = 8）. The recovery was in the range of 93.3% - 102.7%. This method is applicable to the determination of trace extractable mercury in textiles with Oeko-Tex Standard 100,
