摘　　要：采用溶液聚合方法制备的P(AA-co-AM)高吸水性树脂,从吸附时间、树脂质量、混合染料初始浓度及浓度比、钠离子浓度等方面研究了该树脂对甲基橙和甲基紫混合染料的吸附性能。结果表明:室温下,甲基紫的吸附量总是略大于甲基橙,初始浓度为1 200 mg/L时,树脂对甲基橙和甲基紫的吸附量均达到平衡,分别为826.4和882.3mg/g。此吸附过程符合热力学Freundlish方程。Poly（acrylic acid-co-acrylamide）superabsorbent resin was synthesized by solution polymerization.The adsorption of methyl orange and methyl violet on poly（acrylic acid-co-acrylamide）resin was studied from adsorption time,resin quality,initial concentration and concentration ratio of the mixed dye,and sodium ion concentration.The results indicate that the adsorption capacity of methyl violet is always higher than that of methyl orange at indoor temperature.When the initial concentration of dyes is 1 200mg/L,both the adsorption capacity of methyl orange and that of methyl violet level off,being 826.4and 882.3 mg/g respectively.The adsorption process agrees with Freundish equation.
