A study on the sorption of Zn2+, Ni2+ and Co2+ 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 Zn2+, Ni2+ and Co2+ on Mn-Fe oxide at pH 4.5 was 97, 11.85 and 10 % respectively with selectivity order Zn2+ a parts per thousand << Ni2+ > Co2+. The sorption value of Zn2+ at pH 4.5 onto Fe-Mn oxide reached nearly the same value of Zn2+ 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.
