Abstract
The development of nanocomposites for environmental demands is a challenge due to numerous precautions, including tailoring recyclable agents. In this work, bentonite clay (B. Clay)/manganese ferrite (MnFe2O4) nanocomposites have been fabricated via a solid-state technique that is green, efficient, and scalable. The obtained composites have been characterized using FTIR, SEM, and TEM. From the results, MnFe2O4 was configured in spherical shape during the interaction with B. Clay, reflecting the quality of applications. The studied average maximum height of the roughness (Rtm) changes from 151.7 to 107.3 and increases to 141.5 for pure B. Clay, MnFe2O4, and the nanocomposite, respectively. The surface area for the nanocomposite was around 85.45 m(2)/g compared with 57. 46 m(2)/g for MnFe2O4. The magnetic domain has been enhanced exponentially to be 19.93 emu/g after solid synthesis of MnFe2O4 with B. Clay. The adsorption property was more significant in the case of MnFe2O4/B. clay to reach 71.6% decolorization of methylene blue (MB). Other-wise, under light illumination, the phytoremediation Fe3+& nbsp;is reduced to Fe2+, accelerating switching on/off Fe3+/Fe2+ cycle stability to exhibit strong hydroxyl radicals able to destroy MB within 8 min. Also, at 100 mg/ml concentration, the prepared MnFe2O4/B. Clay was aggressive against Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, and Escherichia coli.
