Magnetic Nano Particles as powerful adsorbents for removing of metal ions from aqueous solutions

This article reviews and discusses about the recent developments in using of Magnetic Nano Particles (MNPs) for extraction some kinds of metals from its aqueous solutions. These metals include Zr, U, Cu, V, Co, Ni, Zn, Hg, Pb, Cr, Cd, Au and Trans uranium elements. Adsorption properties of synthesized MNPs for removing of each element were compared with similar ones in conventional method of separation. Therefore it is individually noticed to the recent reported ways in solvent extraction and ion exchange methods for metals. Promising adsorption characteristics and simpler hydrometallurgical performance for each applied MNPs have been identified. For instance in Zirconium separation a functionalized MNP by tributyl phosphate (TBP) has distribution coefficient value of 44 times greater than similar extraction in SX and IX methods.
