Abstract: “This paper mainly discussed the performance of photocatalysts which are prepared cation exchange resin and TiCl3 precursor via heat treatment process to enhance their photocatalytic potentials. The morphology and size of TiO2 photocatalyst was well ordered spherical shape and average diameter of 0.30 ~0.45 mm with well dispersed by TiO2 on the surface of spherical activated carbon. TiO2 supported on spherical activated carbon contains two different phases; anatase (83%) and rutile (17%). The TiO2 photocatalyst had high specific surface area of 1,649 m2/g and high total pore volume of 1.61 cm3/g. Adsorption characteristics and photocatalytic activity of TiO2 photocatalyst were evaluated by the removal of humic acid from waste water model aqueous solution. Catalyst dosage, initial humic acid concentration, and coexisting ions have influences on the photocatalytic degradation of humic acid. The degradation of humic acid by meso-TiO2/SAC was dependent on catalyst dosage, initial its concen”
