Abstrakt: A study on the sorption of Zn, Ni and Co onto mixed oxide of Mn and Fe obtained at different hydrothermal conditions and its organic hybrid film modified with polyacrylamide (Mn-Fe oxide/PAM) has been examined. The characterization of inorganic oxides and its composite samples were performed using XRD, SEM, FTIR, XRF and DTA-TGA techniques. The percent sorption of Zn, Ni and Co on Mn-Fe oxide at pH 4.5 was 97, 11.85 and 10 % respectively with selectivity order Zn ≫ Ni > Co. The sorption value of Zn at pH 4.5 onto Fe-Mn oxide reached nearly the same value of Zn onto its composite. So, the new compound of Fe-Mn oxide has promising uses for separation of zinc ions while its composite can be used for removal all of these cations. [ABSTRACT FROM AUTHOR]
