摘要
采用电感耦合等离子体质谱(TCP-MS)法测定硬聚氯乙烯(PVC-U)饮水管材(件)中的痕量铅、镉、锡、汞,对影响测量结果的因素进行了分析。利用该法测定铅、镉、锡、汞的检出限分别为0.0028、0.0025、0.0052、0.0033μg/L,回收率为84.60％～94.30％,测定结果的相对标准偏差小于4.23％。
The trace Pb, Cd, Sn and Hg in the rigid polyvinyl chloride pipes ior drinking water supply were determined by inductively coupled plasma-mass spectrometry( ICP-MS). The detection limits of the method were 0.0028ug/L (Pb),0.0025μg/L(Cd),0.005 2μg/L( Sn) , 0.003 3μg/L(Hg). The recovery was 84.60%-94.30% . RSD was less than 4. 23% .
