In the present paper an attempt made to degrade effluent of paper mill under Photo catalytic condition. Lab scale model instrument fabricated for conductingAdvanced oxidation process. Titanium-Titaniumoxide prepared and used as catalytic surface. The metal-metal oxide film characterized by SEMand XRD analysis. Effluent of permill then subjected to photo catalysis. COD, UVabsorbance, lignin contentmeasured at regular time intervals. At natural PH 6-7 and temperature conditions, at flowrate of 45min per liter through coaxial photo catalytic reactor, using 36WUVlamp, with constant aeration under laboratory conditions 70%of lignin removed in 150 min. in presence of 7.2ï‚´ 10-2MH2O2 80%of lignin degraded in 150 min.
