| Abstract: | The photocatalytic degradations of Acid Red G and Reactive Brilliant Red K-2G by TiO 2 suspension under the condition of the ultraviolet irradiation were studied.The influences of TiO 2 dosage,the structure and initial concentration of dyes and pH were investigated.The results showed that when the TiO 2 dosage was 3 g/L,the catalytic degradation rates of two dyes reached the maximal value and the degradation effect on basic condition(pH=8.5) was better than that on acidic conditiono (pH=5.5). |
