【摘要】 建立采用氢化物发生电感耦合等离子发射光谱(HG-ICP-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0.002 2 mg/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。更多还原

【Abstract】 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 0.11μg/L.The minimum detection quantity was 0.0022 mg/kg.The RSD was 4.9% at a level of 20.0μg/L and 6.3% for 5.5μg/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.更多还原
