Recent advances and prospects of catalytic advanced oxidation process in treating textile effluents

“…US can enhance the mass transfer rates of solutes and improve the surface properties of solid particles. Recent researches focus on hybrid techniques such as US/O 3 , US/H 2 O 2 , US/UV, US/Fenton, UV/US/TiO 2 , UV/ US/ZnO, and UV/US/O 3 to enhance the degree of mineralization of pollutants (Wu 2007). Ultrasonic irradiation combined with heterogeneous catalysts is the most commonly used for dye degradation (Lin et al 2008, Zhang et al 2009b, Eren 2012).…”

Photodegradation of C.I. Reactive Red 2 in UV/TiO2-based systems: Effects of ultrasound irradiation

“…The enhanced mass transfer and phase transfer properties around solid surfaces caused by US could accelerate the oxidation. The combination of US with other techniques such as UV [4], S 2 O 8 2− [5], TiO 2 [6,7], O 3 [8,9], H 2 O 2 [ [10][11][12], H 2 O 2 /Fe 2+ [10,13], UV/US/TiO 2 [14][15][16][17], UV/US/ZnO [4] and UV/US/O 3 [9] increases the efficiency of the decomposition and removal of pollutant. However, for some compounds, conflicting results exist concerning the effects of such process parameters as pH, US frequency, temperature and additional oxidants on the rate of sonochemical degradation.…”

Effects of TiO2 dosage, pH and temperature on decolorization of C.I. Reactive Red 2 in a UV/US/TiO2 system

“…The enhanced mass transfer and phase transfer properties of solid surfaces caused by US irradiation can accelerate oxidation. Combining US irradiation with other techniques such as UV [3], TiO 2 [4,5], O 3 [6,7], H 2 O 2 [8][9][10], UV/ZnO [3], UV/O 3 [7], UV/Fe(III) [11], and UV/TiO 2 [12][13][14][15][16] …”
