Abstract
The modification of silica-coated magnetite nanoparticles with silver tungstate has been reported to form an effective heterogeneous photo-Fenton catalyst (Fe@AgW) for wastewater treatment. The prepared nanocomposite was analyzed and characterized with the help of SEM, TEM, Powder XRD, BET, UV-DRS, and FT-IR spectroscopy. The nanocatalyst was successfully investigated for mineralization of model cationic and anionic dyes representing industrial effluents pollution and colorless pollutant bisphenol A. The degradation of methylene blue (MB) and methyl orange (MO) was up to 92% and 82%, respectively, using Fe@AgW nanocomposite as a photo-Fenton catalyst. The nanocatalyst was also tested against pathogenic bacterial strains to explore its broad-spectrum use for water treatment. The material owns its desired properties such as economic, high efficiency, simple reaction conditions, and effortless magnetic separation for its potential broad scope applicability in water treatment.
