Abstract: The treatment of azo-dye wastewater using titanium dioxide (TiO2) nanoparticles on porous carbon media was evaluated in this research. The porous carbon media was prepared using resorcinol and formaldehyde via the oil-in-water emulsion technique with the sol-gel process. Drops of titanium isopropoxide (TTIP), isopropy1 alcohol, and water into the as-prepared media followed by calcination at 700-900*C for 2 Ihrs were used to impregnate TiO2 particles onto the surface of porous carbon media. The morphologies of TiO2 nanoparticles on porous carbon were investigated using SEM. From physical appearance found that the small TiO2 particles are homogeneously immobilized on the spherical carbon particles. The crystal structures of porous carbon media and TiO2 were investigated using XRD. The result indicated that the amorphous carbon structure was clearly seen at a calcination temperature of 900*C, and TiO2 particles are mainly rutile structures. The as-prepared TiO2 nanoparticles on porous carbon media have studied an application for wastewater treatment by using both photocatalytic and absorption properties of the materials. The experiment's study revealed that the reactive black 5 dye could be rapidly removed from the simulated wastewater, and the best remover efficiency came from the sample with calcination temperature at 900 C.
