Gelatin (GEL) and poly(vinyl alcohol) (PVA) based semi-interpenetrating polymer network (semi-IPN) hydrogels were prepared as a water adsorbent for cationic dye (methyl violet, MV) sorption. For this case, chemically cross-linked copolymer of an acrylamide/4-styrenesulfonic acid sodium salt (AAm/SSS) copolymer with PVA and/or GEL was prepared by polymerization of aqueous solution of acrylamide (AAm) and 4-styrenesulfonic acid sodium salt (SSS) using ammonium persulfate/N,N,N',N'- tetramethylethylenediamine as a redox initiating pair in the presence of poly(ethylene glycol)diacrylate as a cross-linker. FT-IR analysis was used to identify the presence of different repeating units in the semi-IPNs. Surface morphology was characterized by using a scanning electron microscopy technique. Some swelling and diffusion characteristics were calculated for different semi-IPNs and hydrogels prepared under various formulations. Water uptake and dye sorption properties of the cross-linked polymeric systems, such as AAm/SSS, AAm/GEL/SSS, AAm/PVA/SSS, and AAm/GEL/PVA/SSS hydrogel systems, were investigated as a function of chemical composition of the hydrogels. MV is used in sorption studies.
