Water sorption studies and adsorptive features of acrylamide based hydrogels as semi-IPNs and composites

Akrilamid esaslı yarı-IPN ve kompozit hidrojellerin su soğurum çalışmaları ve adsorpsiyon özellikleri


In this study, sorption behaviors of water absorbing materials on the basis of acrylamide copolymers as semi- IPNs and composite systems have been investigated. Highly swollen hydrogels made by the polymerization of acrylamide with some hydrophilic co-monomers, some linear polymer and some clays were investigated as a function of composition to find materials with swelling and sorption properties of some metal ions, some pollutant-organics and some dyes. The hydrogels, the semi-IPNs and the composites were prepared by γ-irradiation or free radical solution polymerization in aqueous solutions of monomers and some multifunctional crosslinkers. Swelling experiments were performed in water or other swelling media at 25°C, gravimetrically. For sorption of some metal ions and some dyes into the hydrogels was studied by batch sorption technique at 25°C. This review introduces water sorption studies and adsorptive features of acrylamide based hydrogels as semi-IPNs and composites, synthetic methods, the hydrogel characteristics and their applications.
