| 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 |
