Description:
Photocatalytic degradation of methylene blue (MB) in TiO"2 aqueous suspensions using microwave (MW) powered electrodeless discharge lamps (EDLs) was studied. MB of initial concentration 100mg/l was mainly decomposed in the process of photocatalytic degradation using EDLs (PCD/EDLs) after 15min of irradiation. The corresponding mineralization efficiency was 45%. The influence of factors as EDLs, solution volume and TiO"2 catalyst dosage on the decomposition of MB in the PCD/EDLs process was also investigated. The optimal decomposition efficiency was observed when EDLs-4 (four 10mmx50mm EDLs), solution volume of 50ml and TiO"2 catalyst dosage of 1-4g/l were used in the study. The PCD/EDLs process was promising in treating MB polluted water.
