Ozonation was performed for an effective removal of bisphenol A in laboratory scale batch reactor under various experimental conditions including the Al2O3 catalysts dosage, UV irradiation and temperature. Flow rate of ozone 1.0 L min−1 and ozone concentration of 75 ± 5 mg L−1 was maintained constantly, and the pH, COD and TOC were measured in 10 min intervals during oxidation processes for 60 min at 20oC. Our results confirmed that the O3/UV, O3/UV/Al2O3 in the ozonation improved the removal efficiency of both COD and TOC in solution compared with O3 process alone. The pseudo first-order rate constants for the elimination of COD and TOC were calcluated to be 3.58 × 10−4 sec−1, 1.58 × 10−4 sec−1 and 7.98 × 10−4 sec−1, 3.42 × 10−4 sec−1 and activation energy was 1.44 kcal·mol−1 and 2.32 kcal·mol−1 at 20oC, respectively.
