| 摘 要： | 设计和制备了一种新型多孔多胺化壳聚糖 (P-CCTS)，用FTIR和X射线衍射法表征了产物的结构，研究了P-CCTS对镉(Ⅱ)离子的吸附性能，实验结果表明P-CCTS对镉(Ⅱ)离子有很强的吸附能力，在pH为6左右P-CCTS对镉(Ⅱ)离子的吸附能力最强，溶液中适量NaCl的存在能够显著提高P-CCTS对镉(Ⅱ)离子的吸附容量。

| Abstract: | A novel polyaminated and crosslined chitosan (P-CCTS) was prepared by protecting the amino group in chitosan with benzaldehyde and introducing epichlorodydrin and polyethylene polyamine. The structure of P-CCTS was determined by FTIR and X-ray diffraction. The adsorption properties of P-CCTS for Cd(Ⅱ) were studied. The adsorption capacity of P-CCTS for Cd(Ⅱ) is much higher than that of chitosan (CTS), and dependant on pH and the concentration of NaCl in solution. |
