摘　　要：以Sc,Ge,Y,Rh,Re作内标,用电感耦合等离子质谱法测定水源水中23种元素的含量,23种元素的方法检出限在0.0005～0.3μg/L之间,混合标准溶液平行测定的相对标准偏差不大于6.69%(n=7),饮用水样品的加标回收率在82.0%～116.2%之间。该法可用于饮用水中多种元素的同时测定。Inductively coupled plasma mass spectrometry was applied to determin 23 elements in drinking water by using Sc, Ge, Y, Rh, Re as an internal standard. The experimental results showed that the method determination limits ranged from 0.000 5 to 0.3 μg/L Recoveries of spiked drinking water samples were in the range of 82.0% -116.2% and the RSD was not greater than 6.69% （ n=7 ）. The method is suitable for the simultaneous determination of elements in drinking water.
