摘　　要：探讨了原子荧光法与电感耦合等离子体质谱法在测定饮用水中砷含量方面的不同仪器性能。原子荧光法与电感耦合等离子体质谱法测定砷的检出限分别为0.031μg/L和0.005μg/L,RSD(精密度)分别为3.18%、1.21%和1.63%、0.81%。回收率分别为95.8%—102.5%和98.2%—101.6%。在水中砷的测定方面,电感耦合等离子体质谱法要优于原子荧光法,是一种值得推广的方法。The different instrument characteristics of atomic fluorescence spectrometry （AFS） and inductively coupled plasma-mass spectrometry＇ （ICP-MS） in the determination of As in drinking water were discussed. The detection limits of AFS and ICP-MS were 0. 031μg/L and 0. 005μg/L, respectively, the RSDs （precision） of A FS and ICP-MS were 3.18%, 1.2iM and 1.630%, 0.81%, respectively,the recoveries of As by AFS and ICP-MS varied in the range of 95.8M-102.5% and 98.2%-101.6 % ,respectively. The ICP-MS performed better than AFS in the determination of As in waters ,which was worth popularizing.
