Photocatalytic degradation of methylene blue with Fe3O4/graphene oxide nanocomposite

We need clean water supply for the continuation of life. Rapid industrialization and population growth as a result of fresh water resources are rapidly polluted . In particular, textiles and paints a result of the rapid growth of the industry released dye waste can contaminate groundwater resources. Simple removal of this pollution, inexpensive, environmentally friendly, we take advantage of the photocatalytic degradation of rapid and reproducible method. This method of rendering to break down harmful substances in the active semiconductor using UV radiation environment includes the conversion to innocuous products. In this study; photocatalytic degradation of organic pollutants, Methylene Blue (MB) as a model, with Fe3O4/GO was experimentally examined under UV light. The effect of Fe3O4/GO nanocomposite concentration, MB concentration, salt concentration, UV light (UV-A, UV-B, UV-C), pH and time on MB photodegradation was investigated. The photocatalytic removal with the highest energy of UV-C light was found to be excessive. As increasing concentration of composite, the photocatalytic removal increased whereas the concentration of methylene blue dye pollution increased, photocatalytic removal decreased. It was observed that the best contamination removal was found at pH = 11 and when the salt effect was examined, it was seen that the salt which increased the photocatalytic activity most was the NaHCO3 salt. Fe3O4/GO nanocomposite indicated excellent photocatalytic activity. The results were found to be capable of solving the environmental problems of interest.
