| 摘 要： | 以过硫酸铵为引发剂,戊二醛、N,N’-亚甲基双丙烯酰胺为交联剂,采用水溶液聚合法使壳聚糖与丙烯酰胺、丙烯酸进行接枝共聚。制备了一种新型壳聚糖接枝丙烯酰胺-聚丙烯酸吸附材料并应用于Hg(Ⅱ)的吸附研究,考察了原料配比、pH、溶液浓度、吸附时间对吸附性能的影响。结果表明:丙烯酸质量分数为25%、pH=5、吸附时间为200 min时,复合材料表现出最佳吸附性能。

| Abstract: | A new absorbent material was prepared from chitosan, acrylamide and acrylic acid by cross-linking reaction and solution polymerization, using ammonium persulfate as the intiator and glutaradehyde and N,N'-methylenebisacrylamide as the cross-linking agent. Its adsorptive property to adsorb toxic Hg(II) ions was studied. When the mass fraction of acrylic acid was 25%, pH=5 and adsorption time 200min, the adsorption behavior of Hg2 was better. |
