Synergistic Degradation of Methyl Orange in an Ultrasound Intensified Photocatalytic Reactor
摘要
Abstract
This research proposed an original circulatory ultrasound (US) directly intensified photo- catalytic reactor. Using Degussa TiO2 as photocatalyst model, the synergis and effects of opera , and dye methyl orange (MeO) as pollutant tic effects of sonolytic and photocatalytic process in this reactor were investigated, tion parameters i.e. US power, flow rate on reactor performance were studied. The TiO~ dosage, results showed circulating liquid velocity and air that the combination of sonolysis and TiO2 photocatalysis results can have a large synergetic effect in this reactor, and the synergy value is as high as 2.26 ; every parameter has an optimal value within experimental scope as follows : US power 600 W, TiO2 dosage 3 g/L, circulating liquid velocity 4.05 × 10^-2m/s and air flow rate 200ml/min. Under this condition the 1 h degradation rate of MeO is 91.74%.关键词
