| 中文摘要: |
| 以壳聚糖、苯甲醛为原料,乙醇为溶剂,合成希夫碱;用乙二醇二缩水甘油醚为交联剂,在酸性条件下脱保护,以环氧氯丙烷和四乙烯五胺对交联树脂修饰,合成多胺基壳聚糖交联树脂。以石腊为溶剂,PEG-2000为致孔剂,司本-80为乳化剂,形成了多胺基壳聚糖含孔树脂。在室温和pH=7时,壳聚糖树脂对Cd（Ⅱ）吸附量达123.54 mg/g,致孔后的树脂吸附量达315.10mg/g。 |
| 英文摘要: |
| The Schiff-base was prepared by chitosan reacting with benzaldehyde,and ethanol used as solvent.Then through cross-linked agent with ethyleneglycoldiglycidylether under acidic conditions,and modified with epoxychloropropane and tetraethylenepentamine,the chitosan cross-linked resin with polyamino group was synthesized.Next step,the chitosan cross-linked resin with polyamino group was treated with PEG-2000 as pore-forming agent and Span-80 as emulgent in liquid paraffine,and the porous chitosan cross-linked resin with polyamino group was obtained.The chitosan resin was found that the adsorption amount of Cd(Ⅱ) was up to 123.54 mg/g,and after pore-forming,the adsorption amount could reach 315.10 mg/g. |
