马来酸酐/丙烯酸水凝胶对亚甲基蓝染料的吸附
Adsorption of Methylene Blue Dye by Maleic Anhydride/Acrylic Acid Hydrogel
摘要
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.关键词
