Improper disposal of effluent contaminated with organic dyes may cause environmental problems. In this context, the ZnO semiconductor and the ZnO/ZnFe2O4 magnetic composite were prepared by the combustion method. The synthesized materials showed adsorption and photocatalysis properties for elimination of methylene blue dye from aqueous medium. About 88% of the methylene blue was eliminated by ZnO and 63% by the composite. In the photocatalysis process, a low cost visible light source was used. These materials can be regenerated by a photo-Fenton process. Moreover, the ZnO/ZnFe2O4 composite can be separated from the reaction medium by a magnetic field.Downloads
