%X Study was carried out for the removal of 2,4-Dichlorophenoxyacetic acid (2,4-D) from aqueous solution by using the two-phase ozonation system of water and perfluorodecalin organic solvent loaded with ozone. Perfluorodecalin has a high ozone stability and solubility. 2,4-D was used to examine the efficiency of the two-phase ozonation system. During the experiments, effects of pH, the initial concentration of ozone, and free radical scavenger on the removal rate of 2,4-D were investigated. The results showed that the efficiency of two-phase ozonation increased with the increase of the initial pH in the water phase. Increasing the initial molar ratio of perfluorodecalin loaded O3/2,4-D had a positive effect on the degradation of 2,4-D in the two-phase ozonation system. It was also observed that tert-butyl alcohol, a free radical scavenger, had no significant negative effect on the two-phase ozonation.
