摘要
以壳聚糖为基料,在氮气保护下,用硝酸铈铵做催化剂,采用丙烯酰胺接枝改性方法,制备了一种新型的天然高分子絮凝剂,利用高岭土悬浊液模拟水样,对生成的接枝共聚物的絮凝效果进行了评价,并利用折光指数增量法测定了接枝产物的接枝率。
A new kind of natural macromolecule flocculants was prepared from Chitosan by grafting polyacrylamide under nitrogen atomosphere by using cerium ammonirm nitrate as the catalyst.Then,the experimental synthesised compound is used to purify water samples mixed with kaolin in order to evaluate its ability of flocculation.Also,the grafting ratio of the compound is measured by the method of specific refractive index increment measurement.
