摘要: 用国产高效离子交换色谱仪及国产阴离子交换树脂研究了分离Cl-、Br-、Ⅰ-的条件,以硝酸钠为洗脱液,在三十五分钟内完全分离了上述三种离子。进行了一些样品的定量测定。用无换向阀的予柱富集测定了去离子水中ppb级的Cl-。从软硬酸碱理论的观点讨论了Cl-、Br-.Ⅰ-的色谱行为,得出了用结构参数及实验条件估算分配系数的经验式:1gD=0.24φg[B]-1g[B]+0.49φ+0.61。
Abstract: The conditions of HPIECseparation of Cl-, Br- and I- were studied. The ions were separated within 35minutes by using NaNO3 as an eluent. the chloride and bromide contents of.some samples were determined. The trace amounts (ppb order) of chloride in pure water were determined by using a pre-column without a four or six way valve.The IECbecaviouf of Cl-, Br- and I- was interpreted from the theory of hard and soft acids and bases. The following experimental formula was obtained.lgD= 0.24φlg[B]-lg[B] + 0.490 + 0.61 where Dis the distribution coefficient of an anion, [B] is the concentra-tion of the eluent, φ is the softness of the anion as a base.
