Synthesis, Physicochemical Properties, and Biological Activity of the Bentonite/Iron Oxide Composite

The powdered bentonite/iron oxide composite material was synthesized by chemical co-precipitation. The grain size composition, morphology, crystal structure, porosity, and thermal stability of the obtained powder were investigated. It was established that iron oxide exists in the composite as the ma...

Description
Summary:The powdered bentonite/iron oxide composite material was synthesized by chemical co-precipitation. The grain size composition, morphology, crystal structure, porosity, and thermal stability of the obtained powder were investigated. It was established that iron oxide exists in the composite as the maghemite/magnetite solid solution with the formula Fe 2.950 O 4 . An increase in the viability of the bacterium Escherichia coli M-17 after culturing in the nutrient medium in the presence of the synthesized bentonite/iron oxide powder was found.
