摘要

利用化学共沉淀法制备的Fe₃O₄为磁核,以壳聚糖(CS)为基体,戊二醛为交联剂,制得磁性壳聚糖微球(MCSM),并通过四乙烯五胺(TEPA)进行改性,合成了氨基功能化磁性壳聚糖微球(TEPA-MCSM)。对TEPA-MCSM的粒径、结构以及磁性进行了表征,并研究TEPA-MCSM对废水中Pb²⁺的吸附性能。结果表明,TEPA-MCSM呈规整的球形,粒径在250～350μm之间且具有一定的磁响应性。TEPA-MCSM对Pb²⁺的吸附遵循准二级动力学模型和Langmuir等温吸附模型,TEPA-MCSM对Pb²⁺的最大吸附量为277.78mg/g,重复使用5次后仍能达到初始吸附量的77.4%,具有良好的重复使用性能。

Abstract

Fe₃O₄ synthesized via chemical co-precipitation was used as the magnetic core,chitosan (CS) as the matrix,and glutaraldehyde as the cross-linker to produce magnetic chitosan microspheres (MCSMs).The obtained MCSMs were further functionalized with tetraethylenepentamine (TEPA) to prepare amino-functionalized magnetic chitosan microspheres (TEPA-MCSMs).The particle size,structural features,and magnetic properties of TEPA-MCSMs were characterized.Furthermore,the adsorption performance of TEPA-MCSMs toward Pb²⁺ in aqueous solution was investigated.The results showed that TEPA-MCSMs exhibited regular spherical shapes,with particle sizes ranging from 250μm to 350μm,and pronounced certain magnetic responsiveness.The adsorption behaviour of Pb²⁺ by TEPA-MCSMs followed the Langmuir isotherm model and the pseudo-second-order kinetic model.The maximum adsorption capacity of TEPA-MCSMs for Pb²⁺ was 277.78mg/g.After five consecutive adsorption-desorption cycles,it still retained 77.4% of its initial adsorption capacity,demonstrating excellent reusability.
