摘要

以丙烯酰胺(AM)、二甲基二烯丙基氯化铵(DMDAAC)为接枝共聚单体,分别采用热引发、光引发和超声波引发方式制备壳聚糖基絮凝剂CS-P(AM-DMDAAC)。采用红外光谱和扫描电镜(SEM)对三种不同引发方式制备出的絮凝剂进行表征。以高岭土模拟水样为处理对象,采用三种絮凝剂进行絮凝实验,结果表明光引发下制备产品的絮凝效果要明显优于其它两个产品,同时分析了出现这一现象的原因。
        The acrylamide(AM) and dimethyldiallyl ammonium chloride(DMDAAC) were used as grafted monomers,and heat-initiation,ultraviolet-initiation and ultrasonic-initiation were used to prepare chitosan based flocculant CS-P( AM-DMDAAC). FT-IR and SEM were used to characterize the structures of the three flocculants.Kaolin suspension was used to compare the performances of the three flocculants. Results indicated that flocculant prepared by UV-initiation performed better than the other two products. The reason of this performance was analyzed.
