摘要

壳聚糖是一种天然无毒的吸附剂，非常适合用于重金属和抗生素的去除。本研究采用聚丙烯乙二醇和衣康酸酐对壳聚糖进行改性，改善壳聚糖的力学性能，成功制备了聚丙烯乙二醇-衣康酸酐-壳聚糖吸附剂。采用傅里叶变换红外光谱(FTIR)、扫描电镜(SEM)、热重分析和x射线光电子能谱(XPS)对吸附剂进行了表征和分析。考察了不同条件对Pb2+和头孢氨苄吸附的影响。Langmuir吸附等温线模型表明，Pb2+和头孢氨苄的最大吸附量分别达到431.73 mg g−1和153.72 mg g−1。探讨了Pb2+和头孢氨苄的可能吸附机理。

The preparation of a novel modified chitosan: application to the removal of lead and cephalexin

As a natural, non-toxic adsorbent, chitosan is well suited for the removal of heavy metals and antibiotics. In this study, chitosan was modified with polypropylene glycol and itaconic anhydride to improve the mechanical properties of chitosan, and the polypropylene glycol-itaconic anhydride-chitosan adsorbent was successfully prepared. The adsorbent was characterised and analysed by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis and X-ray photoelectron spectroscopy (XPS). The effects of the different conditions on the adsorption of Pb2+ and cephalexin were investigated. The Langmuir adsorption isotherm model showed that the maximum adsorption capacities of Pb2+ and cephalexin could reach 431.73 mg g−1 and 153.72 mg g−1, respectively. The possible adsorption mechanism of Pb2+ and cephalexin was discussed.
