摘要

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 films were irradiated at doses of 5, 10 and 15 kGy using Co-60 gamma-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 were used for removal of basic Violet 7 dye. The adsorption of the dye match with the Langmuir model across chemical monolayer adsorption performance. 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).
