Özet
The discharge of organic dyes from industrial plants processing pharmaceuticals, textile fabrics, leather, and petrochemicals is a great concern in terms of water contamination. Even in small amounts less than 1 mgL-1 , dyes have serious effects on the water quality of the aquatic environment. In this study, methylene blue was chosen as a model to represent the azo-dye class that is non-biodegradable, toxic and mutagenic. Photocatalytic degradation is a sustainable and eco-friendly remediation process to eliminate the undesired effects of dye contamination. The morphology of the catalyst highly influences the properties and the efficiency of the catalytic reaction. A novel composite magnetic nanoparticle was synthesized in core-shell structure and characterized with the aid of Scanning Electron Microscope (SEM) images combined with an elemental distribution image (EDX mapping), Zeta Potential, Dynamic Light Scattering (DLS) analyses and Raman Spectrometer. The electronic properties of the fabricated material were enlightened by Mott Schottky measurements. In optical studies, direct band-gap energies were calculated with the aid of Ultraviolet-Visible Diffuse Reflectance Spectroscopy (UV-DRS). The effective photocatalytic degradation of methylene blue in aqueous medium was maintained with optimum parameters defined within the study. The results support the applicability of the proposed novel magnetic nanoparticle as a catalyst for the degradation of methylene blue in aquatic environment.
