We suggest the possibility of a continuous treatment method for gaseous organic pollutants in liquid phase. Among these pollutants, toluene was selected as hard to dissolve in water and formaldehyde as intermediate water soluble compound. In this study, sonophotocatalytic reaction system was investigated for simultaneous collection and degradation of these pollutants in a fluorocarbon (FC) / water emulsion solvent. Toluene is directly pyrolyzed inside the cavities generated by ultrasound and is also degraded by reaction on the interfaces with the OH radical generated by photocatalytic reaction. Formaldehyde reacted in water phase with H_2O_2 and the OH radicals generated by ultrasound and photocatalysis. And both organic pollutants were decomposed in high rates. It was the results show that water soluble compounds as well as hard soluble compounds can react efficiently in the different phases with this method, as it depends on characteristic of pollutant. It was demonstrated for the simultaneous degradation of toluene and formaldehyde in this study.
