The present work describes the preparation of titanium oxide impregnated polyacrylamide hydrogel (TiO2/PAM) by in-situ polymerization technique. The prepared hydrogel was characterized by fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and x-ray diffraction (XRD) techniques. The physical properties (solvent content, swelling behaviour, porosity) of hydrogel were also studied by ASTM method. Further, results are revealing the formation of composite hydrogel with improved properties. Thus, obtained prepared hydrogel was used for removal of methyl orange dye from laboratory prepared water samples. The methyl orange removal efficiency and kinetics was evaluated by UV-Visible spectroscopy in different conditions. The results indicate the improvement in dye removal capacity due to impregnation of metal oxides in hydrogel matrix.
