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.
