Abstract 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 60Co 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).

Bagasse Waste

According to the availability of bagasse waste and increasing environmental concern, this research is focused on the preparation of polylactic acid (PLA)/bagasse carboxymethyl cellulose (CMCB) composite in order to improve the thermal and mechanical properties of PLA/CMCB film. PLA were mixed with CMCB at different ratios (1, 2, 4 and 8%, w/w of PLA), by kneading in two roll mills and then hot pressing into film. The results revealed that the addition of CMCB had significant effects on PLA composites properties. Differential scanning calorimetry (DSC) measurement indicated that the presence of CMCB accelerated the reduction of glass transition, and melting temperatures. Moreover the CMCB could improve the storage modulus of PLA composites at high temperature because its cold crystallization was developed. At room temperature, the tensile strength and elongation of PLA composite (but not modulus) were not significantly different with an increase of CMCB contents.
