摘要

采用自由基聚合法制备了壳聚糖、丙烯酸与巴豆酸复合的水凝胶纳米复合材料。KPS作为引发剂，MBA作为交联剂。Ch-g-P(AA-co-CA)纳米复合材料是一种强大的污染物吸收剂。使用该组合物去除水中的Cr (III)。采用场发射扫描电镜(FESEM)和红外光谱(FTIR)对纳米复合材料的结构和形貌进行了表征。利用这些速率对Cr (III)吸附动力学进行了研究。准二级动力学表征了吸附过程。水凝胶纳米复合材料通过吸附(III)有效去除铬。

Removal of Cr (III) by using Chitosan-Grafting-Poly(Acryl Acid-Crotonic Acid) Characterization and Kinetic Study

Hydrogel nanocomposites were prepared using free radical polymerization chitosan and acrylic acid (AA) in combination with crotonic acid. KPS was employed as the initiating agent, while MBA functioned as the cross-linking agent. The nanocomposite of Ch-g-P(AA-co-CA) is a powerful pollutant absorber. Cr (III) was removed from the water using the combination. Field emission scanning electron microscopy (FESEM) and infrared spectroscopy (FTIR) were used to examine the nanocomposites’ structure and morphology. The kinetics of Cr (III) adsorption was studied using these rates. Pseudo-second order kinetics characterize the adsorption process. Hydrogel nanocomposite efficiently removes Cr by adsorption (III).
