A chelate compound wherein a chelate-forming moiety is attached to a base compound having an amino group and at least a part of the amino group is in the form of a halide salt. A specific example of the halide salt is hydrochloride. As the base compound, a chitosan having a glucosamine skeleton is preferred. Also, chitosan beads are usable. The chelate compound is produced by reacting the base compound having an amino group with an aldehyde group of an aromatic cyclic compound, aromatic cyclic compound having at least a functional group capable of forming a chelate and the aldehyde group, to form a Schiff base, reducing the Schiff base with a reducing agent and then treating with a hydrohalogenic acid (hydrochloric acid).
一种螯合物,其中的螯合形成分子连接到具有氨基的基化合物上,氨基的至少一部分以卤化物盐的形式存在。卤化盐的一个具体例子是盐酸盐。作为基化合物,优选具有氨基葡萄糖骨架的壳聚糖。此外,壳聚糖珠也可以使用。螯合物的制备方法是将具有氨基的基化合物与芳香族环状化合物的醛基反应,芳香族环状化合物至少具有一个能形成螯合物的官能团和醛基,形成希夫碱,用还原剂还原希夫碱,然后用氢卤酸(盐酸)处理。
