Simultaneous treatment of oil and dye-contaminated water by a novel composite
Source abstract
Abstract
Abstract Expanded Graphite (EG) has been widely used for treating oil-polluted water. Removal of dye pigments from oily wastewater is the biggest challenge for paint industries. So, the present work focuses on treating simultaneously oil and dye-contaminated water by introducing TiO2/ EG composite. EG samples with the highest exfoliation volume have been prepared by microwave irradiation by optimizing time and tested through an oil adsorption study with different oils. TiO2 NPs have been synthesized by the sol-gel method. A novel EG/TiO2 composite has been synthesized by mixing TiO2 NPs in GIC (precursor) and exfoliating the mixture for the optimized irradiation time. A comparative study of the effect of EG, TiO2 NPs, and EG/TiO2 composite on oil and dye-polluted water has been performed in direct sunlight. Results of UV-visible spectroscopy showed that the addition of TiO2 NPs with EG accomplished the dye degradation along with the adsorption of oil from polluted water.
