摘要： 本文用萃取剂[1.2]N263或N235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。

Abstract: The conditions of separation of Cl-, Br- and I- by reversed-phase chromatog-hy using N235-silica gel or N263-silica gel as stationary phase were studied. ions were separated within32 minutes by using NaNO3 as mobile phase. The ride and bromide contents of some samples were simultaneously determined. The hods of determining Vm were studied in detail. The chromatographic behaviour Cl-, Br- and I- on N235 and N263 was investigated. An empirical formula of ulating retention values was obtained.
