Abstract: LaMnO3 perovskite has been used for the treatment of aqueous solution of phenol using stoichiometric amount of H2O2 and combination of TiO2 and UV radiation. The oxidation of phenol was studied with [UV radiation]; [H2O2 and UV]; [TiO2 and UV]; [LaMnO3 and UV]; [TiO2, H2O2 and UV]; [LaMnO3, H2O2 and UV]; to establish the effectiveness of different systems when compared with perovskite catalyst. Results show that the phenol degradation efficiencies decreased in the following order [LaMnO3, H2O2 and UV] > [TiO2, H2O2 and UV] > [LaMnO3 and UV] > [TiO2 and UV]> [H2O2 and UV ] > [UV]. UV-VIS spectra result of phenol degradation shows that as the concentration of catalyst increases, its activity increases. The optimum concentration of catalyst was 0.60 g/L for 100 ppm phenol solution. Perovskite catalyst after reaction is completely regenerated by calcinations at 800°C for 2 h and retains a similar catalytic performance
