Synergistic Effect of Titanium Dioxide (TiO2) and Ionizing Radiation on Thermal and Mechanical Properties of Carboxymethyl Cellulose (CMC) for Potential Application in Removal of Basic Dye from Wastewater

Carboxymethyl cellulose (CMC)/titanium dioxide (TiO2) was prepared using gamma irradiation at different doses. used as a matrix and TiO2 in contents added (0.25, 0.5, 1, 1.5 wt%) filler. The polymer composite films were irradiated doses of 5, 10 15 kGy 60Co γ-ray to form crosslinked network structure. described by diagnostic procedures including X-ray diffractometer, scanning electron microscope (SEM), FTIR well thermal mechanical properties measurements. CMC/TiO2 for removal basic Violet 7 dye. adsorption the dye match with Langmuir model across chemical monolayer performance. Adsorption kinetic dyes set up be regular pseudo second order model. results showed that significantly removed this violet maximum absorption capacity (123.6 mg/g).
