Chongdian Si Kinetics of photodegradation of alizarin green in an acoustic fluidized bed using TiO2 catalyst / Chongdian Si, Jing Zhou, Yuhong Sun, Guangjun Liu, Hongtao Gao // Химия и технология воды. - 2016. - 38, № 4. - С. 378-386. - Бібліогр.: 17 назв. - англ.The kinetics of photodegradation of alizarin green (AG) in an acoustic fluidized bed was investigated using Degussa P25 catalyst and N-doped TiO2 catalyst, respectively. The effects of initial concentration of AG, catalyst amount, initial pH value and liquid flow rate on the photodegradation rates were the main goal of present study. The degradation rate increased with increasing amount of photocatalyst, pH value and liquid flow rate, reached a maximum and then decreased. The degradation rate decreased with increasing initial concentration. According to the Langmuir - Hinshelwood model, the disappearance of the AG followed pseudo-first-order kinetics. Experimental results showed that AG can be degraded effectively by Degussa P25 catalyst and N-doped TiO2 catalyst in an acoustic fluidized bed reactor. N-doped TiO2 catalyst has high and significant photocatalytic activity and in comparison with Degussa P25 catalyst was photocatalyst. Індекс рубрикатора НБУВ: Г544.53
