Abstract:
Phenol photooxidation in a flow reactor of a cylinder shape was studied for systems H2O2 + UV and TiO2 + H2O2 + UV. TiO2 was prepared as cylinder granules 0.3 cm long and 0.2 cm in diameter. Limit liquid flows and concentrations of organics that can be converted in the reactors were estimated. The contributions of various reaction routes (direct photochemical action on the organic compound, OH generation from H2O2, photocatalytic decomposition of H2O2 and organics on TiO2) were estimated and shown experimentally. It has been proved in experiment that in a designed photocatalytic reactor (length 15 cm, mercury lamp middle pressure 250 W) up to 98% of phenol can be decomposed at a concentration of 6 × 10−5 M phenol and a concentration of 10−2 M peroxide at a flow of 21 1 h−1.
