Abstract
In this study, a series of poly (N-cyclohexylacrylamide-co-Acrylamide/Maleic acid) hydrogels were prepared from free-radical copolymerization in water/methanol medium using ammonium persulfate (APS) as a free radical initiator and N,N’-methylene-bis-acryl amide(MBA) as the cross-linker at 60˚C. The synthesized hydrogels were characterized by FTIR, SEM, XRD and TGA techniques. Swelling parameters in water and dye solution were calculated. The effect of two cationic salt solutions on the swelling was studied. The hydrogels showed up to 47.9% removal efficiency towards methylene blue dye adsorption study
