摘要
交联聚苯乙烯树脂经研磨、分选后便可得到粒度均匀的小颗粒树脂(5～15μm)。我们用分选后的树脂合成了一种亚胺基二乙醛肟树脂,将其吸附Cu^(2+)后用作定位金属离子亲和色谱固定相,以甲醇氨溶液为流动相分离胺类化合物。本文详细讨论了胺类化合物在柱上的保留机制以及氨的浓度对样品洗脱的影响。
Iminodialdehydeoxime (IDAO) resins, a new chelating resin, was synthesized by the authors.The IDAO resins modified with copper (Ⅱ) can be used as a stationary phase to separate aminesby Immobilized metal ion chromatography using a mobile phase of ammonia-containing methylalcohol. The retention mechanism of amines on the column and the effect of ligand (NH_3) ontheir retentions have been discussed.
