摘　　要：本文用萃取剂N_(263)或N_(235)为固定液,以硝酸钠溶液为流动相,在HPIEC仪器上研究了分离卤素离子的条件。32分钟完全分离了Cl^(-)、Br^(-)、I^(-),测定了一些样品,结果良好。讨论了卤素离子在高分子胺上的色谱行为,提出了用热力学参数及实验条件估算其保留值的经验公式。The conditions of separation of Cl^(-), Br^(-) and I^(-) by reversed-phase chromatog-hy using N_(235)-silica gel or N_(263)-silica gel as stationary phase were studied. ions were separated within 32 minutes by using NaNO_(3) as mobile phase. The ride and bromide contents of some samples were simultaneously determined. The hods of determining V m were studied in detail. The chromatographic behaviour Cl^(-), Br^(-) and I^(-) on N_(236) and N_(263) was investigated. An empirical formula of ulating retention values was obtained.
