文摘

In this report, it was to investigate that the swelling and dye sorption properties of a series of novel hybrid composite hydrogel sorbent systems containing polysaccharide/clay polyelectrolyte based on acrylamide/potassium 3-sulfopropyl methacrylate and sodium alginate, and clay such as bentonite were synthesized with free radical solution polymerization by using ammonium persulfate/N,N,N’,N’-tetramethylethylenediamine as redox initiating pair in presence of poly(ethylene glycol) diacrylate as a crosslinker. Swelling experiments were performed in water at 25 °C, gravimetrically. The hydrogels, the semi-interpenetrating polymer networks, and the hybrid composite hydrogel systems that synthesized in this study have showed high water absorbency. Some swelling and diffusion properties were calculated, and they were discussed for the hybrid hydrogel systems prepared under various formulations. The equilibrium percentage swelling degree of highly swollen hybrid composite hydrogel systems ranges are 718-2055 %. FT-IR analysis and SEM technique were applied for characterization. For sorption of water-soluble cationic dye such as lauths violet into the hydrogel systems was studied by batch sorption technique at 25 °C. For equilibrium sorption studies, dye sorption percentage, dye uptake performance, and partition coefficient of the hydrogel systems have been investigated. The values of dye sorption percentage of the hydrogels were changed among 87.11-96.39 %. Consequently, the hydrogel systems developed in this study could serve as a potential device for water and dye sorbent.
