Abstract (EN)

In this study, acrylamide monomer and potassium 3-sulfopropyl methacrylate as a comonomer and in order to form a composite structure with sodium alginate as a naturel polymer and bentonite as a clay mineral have been synthesized for the production of chemically crosslinked copolymers. Hydrogel systems were prepared by free radical polymerization in aqueous solution using poly (ethylene glycol) diacrylate as a crosslinker. Structural characterization of prepared chemically crosslinked polymers were tried to determine by using Fourier Transform Infrared Spectroscopy/Attenuated Total Reflectance (FT-IR/ATR). SEM micrographs were taken for determination of surface porosity of hydrogel systems. Dynamic swelling tests were applied at 25oC for the purpose of investigation of swelling properties of crosslinked hybrid hydrogels and semi-IPN hydrogels. According to obtained data, parameters concerning swelling kinetics and diffusion mechanism were calculated. A cationic dye such as lauths violet (thionin) was selected as model molecule to investigate of adsorption properties of hydrogels. It was determined that crosslinked hybrid hydrogels and semi-IPN hydrogels have adsorbed dye of lauths violet from aqueous solutions in high level.
