A master’s thesis was discussed in the College of Science \/ University of Misan, entitled:
\nPreparation and characterization of nano-iron oxide-doped polymers and the study of
\ntheir analytical efficiency in removing some element ions from aqueous solutions. By
\nstudent Nour Sabah Kazim. The study aimed to Preparation of superparamagnetic nano-
\niron oxide by co-precipitation method, then prepare nanocomposites from them with
\ndifferent mixing ratios (1:1), (2:1), ((1:2) with polyurethane PU1 and with polyurethane
\nPU2 and using them as effective adsorbent surfaces to remove heavy metal ions. The best
\nmixing ratio was chosen after conducting the current study. The study also aimed to
\ncharacterize polymeric adsorbents using several techniques: Fourier Transform Infrared
\nspectroscopy FTIR, Atomic Absorption Spectroscopy (AAS), X-rays diffraction (XRD),
\nField-Emission Scanning Electron Microscopy (FESEM) with dispersive X-ray detector.
\nEDX and transmission electron microscopy (TEM), Zeta potential. The study showed
\nthat the adsorption process of ions, Cr (III), Pb (II) Ni (II), Co (II), and Cd (II) on the two
\nsurfaces (Fe3O4-PU1 ), (Fe3O4-PU2) reach equilibrium at time intervals estimated at
\n(60,120,45,30,60 min).<\/p>\n

In the case of temperature, the measured heat of metal ions Pb (II), Cr (III), Cd (II), Co
\n(II), (Ni (II) in this study is at temperatures (300, 303, 310, 318,325 K). , 333) and the
\nadsorption process is appropriate at low temperatures and high concentrations. The
\nresults also showed that Langmuir model is applicable to Cd(II), and Co(II) elements,
\nwhere this model is highly applicable to the first mixture (Fe3O4-PU1). Pb(II), Cr(III),<\/p>\n

and Ni(II) are highly applicable to the Freundlich model for this mixture. The elements
\nCo (II), Cr (III), and Ni (II) are highly applicable to the Langmuir model, and this means
\nthat they are chemically adsorbent, as indicated in the results. – PU1: &gt;Pb (II) Ni (II) Cd
\n(II) &gt; Cr (III) &gt; Co (II) &gt; qmax adsorption quantity of the second mixture (Fe3O4- PU2):
\nCd (II) &gt; Cr (III) &gt; Ni(II)Pb(II) &gt; Co(II) &gt;.<\/p>\n

  5. Ass.Prof. Hind Mahdi Saleh, University of Misan, member and supervisor.
    \nOn this occasion, Prof. Dr. Sabih Jassim Gatea, Dean of the College, met the discussion
    \ncommittee in his office, thanking the efforts they made by taking the trouble to travel in
    \norder to exchange scientific experiences in discussing master&#39;s theses, praising their
    \nefforts in a letter of thanks and appreciation.<\/li>\n<\/ol>\n
