Studies on the mineralization and separation efficiencies of a magnetic photocatalyst
A bench-scale system was used to demonstrate the application of a recently developed magnetic titanium dioxide photocatalyst for the degradation of organics in aqueous systems. The integrated water treatment system included a photoreactor and magnetic separator for the recovery of the magnetic photocatalyst particles. Methylene blue (MB) was used as a test pollutant. The mineralization and bleaching efficiencies of methylene blue using the magnetic photocatalyst were found to be comparable to those of Degussa P25. The magnetic photocatalyst also demonstrated high magnetic separation efficiency. The recycled photocatalyst particles were found to have the same separation efficiency as the fresh catalyst, although the mineralization and bleaching efficiencies were lower.
