摘要
以壳聚糖和海藻酸钠为原料,戊二醛为交联剂,采用水相法制备壳聚糖水凝胶。研究了壳聚糖水凝胶对于Zn2+的吸附性能。结果表明:壳聚糖水凝胶对于Zn2+的吸附符合Langmuir等温方程,热力学行为表明该吸附过程为吸热过程,壳聚糖水凝胶对Zn2+具有较大的吸附能力。
The ehitosan hydrogel was synthesized from chitosan and sodium alginate by aqueous phase with glutaraldehyde as cross-linking agent. The adsorption performance of chitosan hydrogel on Zn2＋ was investigated. The result showed that adsorption of ehitosan hydrogel on Zn2＋ fit the Langmuir adsorption isotherm equation, and thermodynamics behaviors showed that the adsorption was an endothermic process,and the chitosan hydrogel had greater adsorption capacity to Zn2＋.
