Abstract
In this study, it has been investigated that the incorporation of poly(ethylene glycol) and 4-styrenesulfonic acid sodium salt into acrylamide hydrogel during free radical solution polymerization synthesis for novel highly swollen adsorbents and for the effective removal of some potential pollutants from aqueous solutions such as cationic dyes. Poly(ethylene glycol)diacrylate was used as a multifunctional crosslinker. The main purpose of this study was to combine both monomers and a polymer in a new polymeric system. Dye sorption properties of the polymeric hydrogels were investigated by using cationic dye such as Janus Green B. Swelling and sorption studies were carried out at 25°C. For structural characterization, FT-IR analysis and SEM studies were applied. To determine the sorption behaviors of Janus Green B, some sorption parameters such as dye removal capacity, adsorption percentage, and partition coefficient of the polymeric hydrogels were investigated.

Summary
Hydrogels are cross-linked, three-dimensional networked polymers that can swell without dissolving in water. They are three-dimensional reticulated polymers that do not dissolve when contacted with the aqueous environment, show swelling property by holding large amounts of water, and contain many hydrophilic groups. They are called “hungry net structures” due to their high water-holding properties. Having unique properties such as the ease of preparation in different geometric shapes, high water content, soft and rubbery structure, compatibility with biological fluids, and maximum compatibility with the surrounding tissues allow hydrogels to be used as biomaterials [1]-[7]
