Treatment of Wastewater from Methylene Blue Dye and E. Coli Bacteria by High-Performance Fe3O4/rGO/TiO2 Nanocatalyst.
Photocatalysis-based technology has insight into decreasing the disadvantages of traditional approaches and has been identified as an appropriate way to eliminate dyes and bacteria from wastewater. In this work, Fe3O4/rGO/TiO2 photocatalyst material was synthesized by a simple and fast hydrothermal method. The photocatalyst process results showed that Fe3O4/rGO/TiO2 nanocomposite degraded methylene blue dye completely in 4 min. Also, Fe3O4/rGO/TiO2 nanocomposite was very efficient (4.92 log reduction value) for E. Coli bacteria inactivation in 60 min photocatalyst process. The superparamagnetic behavior of Fe3O4/rGO/TiO2 nanocomposite was investigated by VSM analysis and magnetization saturation was obtained at about 38.46 emu/g which gives simple and fast separation from media to Fe3O4/rGO/TiO2 nanocatalyst. The structural and morphology properties of Fe3O4/rGO/TiO2 nanocomposite were studied by XRD, Raman, FT-IR, EDS, FESEM, and TEM analysis. The obtained results confirmed that Fe3O4/rGO/TiO2 nanocomposite is an efficient nanocatalyst for the treatment of MB dye and E. Coli. Bacteria from water, simultaneously.
期刊介绍：
Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
