| 摘 要： | 以壳聚糖为原料，经羟丙基氯化、胺基化，制备了一种新型胺基壳聚糖树脂，研究了该树脂对胆红素的吸附性能。结果表明：胺基壳聚糖树脂的胺基含量比壳聚糖高，该树脂对游离胆红素的吸附在3h基本达到平衡，吸附量随着胺基含量增加而增加，树脂的吸附性能受温度、离子强度影响。胺基壳聚糖树脂对血清白蛋白结合胆红素的吸附量大于壳聚糖，但低于对游离胆红素的吸附。

| Abstract: | A novel aminated chitosan resin was prepared by chitosan Schiff base intermediate, through hydroxylpropyl-chloridization and amination. The adsorption properties of the aminated chitosan resin were investigated. The results showed that the amine-group content for the novel aminated chitosan resin was improved compared with chitosan. The adsorption capacity for dissociated bilirubin was increased with the increment of the amine-group content and related to the adsorption temperature and the ion strength. The adsorption capacity of the resin for combined bilirubin is stronger than that of chitosan. |
