Carboxymethyl cellulose (CMC)/titanium dioxide (TiO2) was prepared using gamma irradiation at different doses. Carboxymethyl cellulose was used as a matrix and TiO2 in different contents was added (0.25, 0.5, 1, 1.5 wt %) as a filler. The polymer composite film were irradiated at doses of 5, 10 and15 kGy using 60 Co γ-ray to form crosslinked network structure. The prepared composite films were described by different diagnostic procedures including X-ray diffractometer, scanning electron microscope (SEM), FTIR as well as thermal and mechanical properties measurements. CMC/TiO2 composite films was used for removal of basic Violet 7 dye. The adsorption of the dye follows the Langmuir model a with chemical monolayer adsorption behavior. Adsorption kinetic of dyes was set up to be regular to pseudo second order kinetic model. The results showed that the prepared composite films significantly removed this basic violet 7 dye with maximum absorption capacity (123.6 mg/g).
