摘要: 以马来酸酐(MA)、 丙烯酸(AA)和丙烯酰胺(AM)为原料, 采用水溶液聚合法制备P(MA-co-AA-co-AM)水凝胶, 并考察不同因素对水凝胶吸附亚甲基蓝染料效果的影响. 实验结果表明: 当亚甲基蓝染料初始质量浓度为1 g/L, 吸附剂用量为1 g/L, 溶液pH=9, 环境温度为20~25 ℃时, P(MA-co-AA-co-AM)水凝胶对亚甲
基蓝染料的吸附效果最佳, 最大吸附量为985.98 mg/L, 去除率达98.60%; 水凝胶对亚甲基蓝的吸附行为符合准二级反应动力学方程和Langmuir吸附等温式.

Abstract: P(MA-co-AA-co-AM) hydrogel was prepared by aqueous solution polymerization using maleic anhydride (MA), acrylic acid (AA) and acrylamide (AM) as raw materials. We investigated the effect of different factors on the adsorption of methylene blue dye onto hydrogels. The experimental results show when the initial mass concentration of methylene blue dye is 1 g/L, the adsorbent dosage is 1 g/L, the solution pH=9 and the environmental temperature is 20—25 ℃, the adsorption effect of P(MA-co-AA-co-AM) hydrogel on methylene blue dye is the best effect, and the maximum adsorption capacity is 985.98 mg/L, the removal rate reaches 98.60%. The adsorption process can be well described by the pseudosecondorder kinetic and the Langmuir model.

Key words: methylene blue, maleic anhydride/acrylic acid, hydrogel, adsorption
