摘要
用水相均匀交联法制备戊二醛交联壳聚糖树脂 ,以三聚氯氰为活化剂 ,合成了三甲胺修饰戊二醛交联壳聚糖树脂 ,研究了该树脂的红外光谱特征及吸附性能。该树脂对铜 (Ⅱ )和牛血清白蛋白 (BSA)的吸附容量分别为 37mg/g和 460mg/g(以折合干重计 ) ,其吸附行为符合Freundlich等温吸附模型。该树脂制备工艺简单 。
The preparation and characterization of trimethylamine modified glutaraldehyde-crosslinked chitosan resin activated with cyanuric chloride, and its infrared spectral properties were studied. The adsorption capacity of the modified crosslinked chitosan resin to copper (II) and bovine serum albumin (BSA) was 37 mg/g (dry weight) and 460 mg/g (dry weight) respectively. The adsorptive were correlated by the Freundlich isotherm equation. The resin has good mechanical strength, and can be used for the separation and purification of proteins.
