摘要
用电感耦合等离子体质谱法(ICP—Ms)测定了地下水中痕量元素(Cd、Co、Cr、Cu、Mn、Mo、Ni、Pb、As、Se、Zn、Ba、Fe),应用在线加入内标校正干扰效应,元素检出限为0.002~0.179μg/L,加标回收率为96.50%-103.10%,相对标准偏差(RsD)〈2.31%。试验结果表明该法测定国家标准参考物质的测定结果与标准值相符。
Inductively coupled plasma-mass spectrometry(ICP-MS) was applied to the determination of trace elements such as Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, As, Se, Zn, Ba and Fe in groundwater and the interferential effect was corrected by the in-line addition of internal standards. The detection limits of those elements are 0.002 - 0.179 μg/L, the recovery rates are 96.50 % - 103.10 %, and the relative standard deviation (RSD) is less than 2.31%.
