摘要: Interpenetrating polymer network (IPN) hydrogels based on chitosan (CS) and poly(acrylic acid) (PAA) were prepared by one-pot strategy. The exhibited porous structure enhanced mechanical strength due to the entrapment of two polymeric networks in IPN. ability adsorb basic dye Nil Blue (BB 12) from aqueous solutions was assessed using UV-VIS spectrophotometer. adsorption amount pH dependent, maximum capacity observed at 10.0. equilibrium achieved within 45 minutes process could be well described pseudo-second-order kinetic model Langmuir isotherm. Furthermore, synergistic interactions between dyes IPN found during process. Thermodynamic parameters revealed sorption an endothermic spontaneous with increasing randomness hydrogel/solution interface. Finally, studies reproducibility su...
