Possible use of magnetic photocatalysts for oxidation/degradation of different water pollutants

Photocatalytic oxidation process, with heterogeneous photocatalysts, as one of the Advanced Oxidation Processes (AOPs), can be effective technology in the oxidation/degradation of different water pollutants. The main problem with manipulation with photocatalyst (usually TiO2 particles in the size range 20-30 nm) is the need to separate them after the photocatalytical oxidation process and reuse them for further process of degradation of pollutants. In this study two different methods (growth of magnetite crystals on the photocatalyst surface and formation of photocatalytic nano-film on the magnetite core) for preparation of magnetic photocatalysts was applied and magnetic technology was used for separation of particles from water. Photocatalysts were successfully prepared and reused with the efficiency of more than 90% and also successfully used for different water pollutants –pharmaceutics and natural organic matter.
