摘要：This study explored the effect on photocatalytic degradation in aqueous solution with high- concentration ammonia where immobilized TiO 2 on glass beads was employed as the photocatalyst. TiO 2 film was prepared via deep coating TiO 2 in a sol–gel system of tetrabutyl titanate precursor and calcinating it at the temperature between 400 to 650 °C. Several crucial factors affecting on the rate of removal of ammonia were investigated. These factors included annealing temperature, catalyst composition, coated times of TiO 2 film, aqueous initial pH, UV exposure time, repetitions times, etc. The results validate the effectiveness as TiO 2 glass beads was employed for photocatalytic degradation treatment in high concentration ammonia solutions.
