Characterization of pure and added zinc magnesium oxide nano particles

Due to the rapid increase in the world population and the number of industries, the demand for clean water has exceeded the water demand in many places. In addition, various pollutants from wastes are sources of water pollution in addition to the main product in different industries. Therefore, it is of great importance to remove these pollutants from waste water Because pollutants and their degradation products are generally toxic and carcinogenic. This poses a serious danger to aquatic organisms. Traditional adsorption processes cannot completely remove toxic dyes due to their limited adsorption capacity. This is why photocatalytic degradation has been used as an effective and environmentally friendly tool in solving this problem. Photocatalytic processes are an environmentally friendly catalytic approach that involves the generation of highly reactive oxygen species such as hydroxyl radicals that perform the degradation processes. In this study, activated carbon (AC) supported ZnOMg, activated carbon supported nickel and iron doped ZnOMg nanoparticle photocatalysts were synthesized by hydrothermal method to be used in photocatalytic degradation of methylene blue. Photocatalytic activities of nanoparticle photocatalysts were investigated for photocatalytic degradation of methylene blue (MB) under visible light at room temperature. Characterization of synthesized nanoparticle photocatalysts; X-ray diffraction (XRD) was characterized using energy dispersive X-ray, EDX and UV-Vis absorption measurements. Photocatalytic degradation reactions were carried out in a photo cabinet under ultraviolet light with different catalyst amounts, various pH and initial concentrations of the dye. For kinetic study, decays were measured with a UV-Vis spectrophotometer. The effects of catalyst amount on reaction kinetics parameters and degradation rate constant were determined.
