Radiation Crosslinking of a Mixture of Polyvinyle Alcohol Methacrylic acid and 2-Hydroxyethyle Methacrylate to Removal of Pollutant Dyes from its Aqueous Solution

Document Type : Original Article

Abstract

 HYDROGELS based on polyvinyle alcohol methacrylic acid/ 2-hydroxyethyle methacrylate [P(PVA-MAAc/HEMA)] were synthesized by gamma-radiation. The prepared hydrogels were characterized by infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA). The results of the adsorption studies reveals the higher adsorption capacity of P(PVA-MAAc/ HEMA), hydrogel for the removal of methylene blue and xylenol orange dyes from aqueous solution.
