| 摘 要： | 以壳聚糖(CTS)包合氧化铝经戊二醛交联反应制备了复合微球作为氟离子吸附剂。主要研究了复合微球对F-的吸附模型和吸附动力学,并考察了再生次数对吸附容量的影响。结果表明复合微球对F-有很强的吸附作用和较快的吸附速率;吸附行为符合Freundlich模型,为吸热过程,吸附表观活化能△E=53.71kJ/mol;复合微球经碱液洗脱再生后能够多次使用。

| Abstract: | In this paper crosslinked chitosan composite microspheres were synthesized by chitosan,Al2O3 and glutaraldehyde,and then were used to purify the water with F-.The isothermal adsorption kinetics and adsorption model of composite microphere for F-had been investigated.At the same time,relationship of adsorption capacity and desorption number was studied.The results showed that the composite microsphere had strong absorption ability for F-and fast absorption rate.The results were satisfied with the Freundlich adsorption model,the adsorption was an exothermic process,and the apparent adsorption activation energy was 53.71 kJ/mol.Composite microspheres could be regenerated by pouring to wash with dilute alkali liquid. |
