(CTS-g-GMA)-g-PMMA多孔吸附剂的制备及其脱色性能

Preparation of the(CTS-g-GMA)-g-PMMA porous adsorbent and its decolroization properties

在保留氨基的前提下,使用甲基丙烯酸缩水甘油酯(GMA)对壳聚糖(CTS)进行化学修饰,产物进一步与甲基丙烯酸甲脂(MMA)接枝共聚,并结合乳化、溶液相转化法制备接枝共聚物-(CTS-g-GMA)-g-PMMA多孔吸附剂,其对于活性艳兰KN-R染液的吸附符合准二级动力学模型;在室温、pH为3的条件下,吸附容量可达到850.9mg.g-1。

Chitosan（CTS）was modified with glycidyl methacrylate（GMA）at pH of 3.8,and then was copolymerized with methyl methacrylate（MMA）.The obtained copolymer solution was emulsified,the phase inversed to form porous adsorbent.Its adsorption of reactive brilliant blue KN-R was in accordant with the pseudo-second order kinetic model.At pH of 3 and room temperature,the adsorption capacity reached at 850.9mg·g-1.
