Several interpenetrating network (IPN) hydrogels were made by free radical in situ crosslink copolymerization of acrylic acid (AA) and hydroxy ethyl methacrylate in aqueous solution of sodium alginate. N,N'-methylenebisacrylamide (MBA) was used as comonomer crosslinker for making these crosslink hydrogels. All of these hydrogels were characterized by carboxylic content, FTIR, SEM, XRD, DTA-TGA and mechanical properties. Swelling, diffusion and network parameters of the hydrogels were studied. These hydrogels were used for adsorption of two important synthetic dyes, i.e. Congo red and methyl violet from water. Isotherms, kinetics and thermodynamics of dye adsorption by these hydrogels were also studied.
几种互穿网络（IPN）水凝胶是通过自由基在水溶液中的原位交联共聚合成的，其中包括丙烯酸钠（AA）和羟乙基甲基丙烯酸酯。N,N'-亚甲基双丙烯酰胺（MBA）被用作共聚交联剂来制备这些交联水凝胶。所有这些水凝胶均通过羧酸含量、FTIR、SEM、XRD、DTA-TGA 和机械性能进行了表征。研究了水凝胶的溶胀、扩散和网络参数。这些水凝胶被用于从水中吸附两种重要的合成染料，即刚果红和甲基紫。还研究了这些水凝胶吸附染料的等温线、动力学和热力学。
