Bioremediation of Wastewater by Iron Oxide-Biochar Nanocomposites Loaded with Photosynthetic Bacteria.

ABSTRACT: It has been reported that bacteria-mediated degradation of contaminants is a practical and innocuous wastewater treatment. In addition, iron oxide nanoparticles (NP) are wastewater remediation agents with great potentials due to their strong adsorption capacity, chemical inertness and superparamagnetism. Therefore, a combination of NPs and microbes could produce a very desirable alternative to conventional wastewater treatment. For this purpose, we first prepared Fe₃O₄/biochar nano-composites, followed by loading photosynthetic bacteria (PSB) onto them. It was found that Fe₃O₄/biochar nano-composites exhibited a high adsorption capacity for PSB (5.45 × 10⁹ cells/g). The efficiency of wastewater pollutants removal by this PSB/Fe_3</
