Development of environmentally friendly materials for efficient pollutant removal is crucial. In this work, a new one-pot green-synthesis iron-based with reductive/adsorption potential was developed and tested remediation Cr(VI) in water. Biogenic iron particles (BioFe) BioFe supported on raw montmorillonite (BioFe-MMT) were synthesized using ferric reducing bacteria consortium (FRB), their structures extensively characterized by Mössbauer spectroscopy, X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy. Moreover, the microbial community assessed. Results indicated that BioFe-based presented dispersed cubic baricite microparticles containing Fe(II) Ca2+ structure, making them ideal remediation. The efficiency from water combination reduction adsorption processes evaluated through kinetics experiments. total chromium more than unsupported no dependence dissolved O2 detected. preparation excellent performance biobased synthesis could lead to low-cost technology.
