Abstract
Bentonite is a kind of crystalline clay mineral with the major constituent of montmorillonite. Bentonite mines should be investigated in different areas with different climatic and environmental conditions. Kerman, is a
province in the southeast of Iran famous for its rich resources of bentonite mines. In the present study, the physical and chemical characteristics of the supplied bentonites from three different mines of Kerman
(Kheirabad, Tang-e Quchan and Horjand) were investigated. Kheirabad sodium bentonite sample was selected as a potent adsorbent of organic and inorganic pollutants due to high swelling index. Besides, magnetite nano
composites were synthesized by stabilizing Fe3O4 nanoparticles on desired bentonite. The properties of nanocomposites were studied using FTIR, XRD, VSM, BET and TEM analyses.
