Abstract
Poly(ethylene glycol dimethacrylate-2-vinyl pyridine)-TiO2 [poly (EGDMA-2-VP)] - TiO2 microbeads were synthesized by suspension polymerization method for photocatalytic decolorization of textile dyes from aqueous solution. The synthesized cross-linked [poly (EGDMA-2-VP)] - TiO2 microbeads were characterized by scanning electron microscopy (SEM), X-ray Diffraction (XRD) and fourier transform infrared spectroscopy (FTIR). To investigate the usability of the obtained microbeads in dye decolorization, the paramreters such as pH, polymer amount, time, and dye concentration were examined both under sunlight and 366 nm UV light. Optimum conditions under which maximum photocatalytic decolorization of the dye were pH 3, polymer amount 0.05 g, dye concentration 30 mg /L and time 5 hours.
