摘　　要：研究并建立了电感耦合等离子体-质谱法(ICP-MS)同时测定地下水中B、P、Br和I的方法,考察了标准之间的相互影响,B、P、Br、I的检出限分别为0.8864、1.286、0.6875、0.1242μg/L。加标回收率在98.60%—104.4%之间,研究了乙酸和乙醇在ICP-MS中的增强效果,发现乙酸的增敏效果优于乙醇。The trace boron,phosphor,bromine and iodine in underground water were simultaneously determined by ICP-MS.The interrelationships of four standards were studied.The detection limits of boron,phosphor,bromine and iodine were 0.8864,1.286,0.6875μg/L and 0.1242μg/L,respectively.The recoveries were respectively 98.60%—104.4%.The enhancement effect of ethanol and acetic acid in ICP-MS were researched,and the results indicated that the enhancement effect of acetic acid was better than ethanol.
