摘　　要：采用电感耦合等离子体质谱法测定饮用水中15种稀土元素,采取内标校正法,以Rh、Re、Bi为内标,结合优化仪器条件和干扰校正方程来消除干扰。15种稀土元素的方法检出限为0.000 2μg/L～0.003μg/L,混合标准溶液平行测定的RSD<6%,饮用水样品的加标回收率为98%～120%。Inductively coupled plasma mass spectrometry （ICP-MS） was applied to determine 15 rare earth elements in drinking water by using Rh,Re,Bi as internal standards and combining optimal instrument conditions with interference correction equation to interference elimination. The 15 rare earth elements method detection lim- its range from 0.000 2 μg/L to 0.003 μxg/L. The experimental results showed the method determine limits can meet for the requirement of determination. Recoveries of spiked samples were in the range of 98% - 120% andRSD was lower than 6%.
