Semi and full interpenetrating polymer network (IPN) type hydrogels were prepared by free radical in situ polymerization of methacrylic acid in presence of chitosan using N,N'-methylene-bis-acrylamide (MBA) and glutaraldehyde (for full IPN) as crosslinker. Several semi and full IPN type hydrogels were prepared by varying initiator and crosslinker concentration and also monomer to chitosan mass ratio. These hydrogels were characterized and used for removal of methyl violet and congo red dye from water. Isotherms and kinetics of dye adsorption were also evaluated.
半互穿和全互穿聚合物网络（IPN）型水凝胶是通过在壳聚糖存在下自由基原位聚合甲基丙烯酸，使用 N,N'-亚甲基双丙烯酰胺（MBA）和戊二醛（用于全 IPN）作为交联剂制备的。通过改变引发剂和交联剂浓度以及单体与壳聚糖的质量比，制备了几种半互穿和全互穿 IPN 型水凝胶。这些水凝胶进行了表征，并用于从水中去除甲基紫和刚果红染料。还评估了染料吸附的等温线和动力学。
