The purpose of this research is to study immobilization of titanium dioxide onto granular activated carbon (GAC-TiO2) by sol-gel method in 3 practices; i.e. (1) wash TiO2 gel before calcination, (2) no wash TiO2 gel, and (3) wash TiO2 gel after calcination. Morphological characteristic, crystal structure and element composition of GAC-TiO2 were analyzed by scanning electron microscope (SEM), X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS), respectively. The results showed that immobilization of titanium dioxide could increase pore of GAC. Practice (3) wash TiO2 gel after calcination, revealed titanium composition and titanium dioxide gel on GAC-TiO2 surface more than practice (2) and (1). Additionally, crystal structure of titanium dioxide in anatase form also found in GAC-TiO2 from practice (3). Treatment efficiency of GAC- TiO2 were examined in term of methylene blue removal. From the results, GAC-TiO2 from all three immobilized practices showed similar treatment efficiency (93.4%, 95.1% and 96.7%, respectively) by adsorption and photocatalytic oxidation processes. Moreover, their treatment efficiency also higher than general GAC (67.5%) which proceeded only adsorption process. In conclusion, immobilization of titanium dioxide onto granular activated carbon (GAC-TiO2) by practice (3) wash TiO2 gel after calcination, was appropriated to prepare GAC-TiO2 for water pollutant control application.
