Photocatalytic decolorization of methylene blue using TiO2/UV system enhanced by air sparging
TL;DR: In this paper, the degradation of wastewater containing an organic dye (Methylene Blue) was investigated in a slurry-type reactor enhanced by air sparging, and the effect of air superficial velocity on the degradation reaction kinetics was investigated and the reaction was found to follow the pseudo second order rate law.
