Title: The Complexes of Bisphosphonate and Magnetite Nanoparticles to Remove Uranyl Ions from Aqueous Phase

Abstract

Using tetraethyl-3-amino-propane-1,1-bisphosphonate (BP) as the functional molecule, we functionalized Fe3O4 magnetic nanoparticles via dopamine (DA) linkage to create a system with an Fe3O4-DA-BP nanostructure, which possesses high specificity for removing uranyl ions from water or blood. This work demonstrates that magnetic nanoparticles, combined with specific receptor-ligand interactions, promise a sensitive and rapid platform for the detection, recovery, and decorporation of radioactive metal toxins from biological environment.

  • Highlights: • Nano magnetite–chitosan films were prepared by casting method. • The efficiency of the prepared films for removing heavy metals was investigated. • The adsorption mechanism was studied using different isotherm and kinetic models. • Films reuse and metals recovery were studied. - Abstract: Nano magnetite chitosan (NMag–CS) film was prepared and characterized with different analytical methods. X-ray diffraction (XRD) patterns confirmed the formation of a pure magnetite structure and NMag–CS nanocomposite. TEM image of the film, revealed the uniform dispersion of magnetite nanoparticles inside chitosan matrix. The adsorption properties of the prepared film for copper, lead, cadmium, chromiummore » and nickel metal ions were evaluated. Different factors affecting the uptake behavior by the composite films such as time, initial pH and film dose were investigated. The adsorption equilibrium attained using 2 g/L of the film after 120 min of reaction. The equilibrium data were analyzed using Langmuir and Freundlich models. The adsorption kinetics followed the mechanism of the pseudo-second-order equation for all metals. The metals regenerated from films with an efficiency greater than 95% using 0.1 M ethylene diamine tetra acetic acid (EDTA) and films were successfully reused for adsorption.« less
  • At constant sulfuric acid activity, constant low total uranium concentration and constant extractant concentration, 1.07 M ionic strength (HCIO/ sub 4/ and NaCIO/sub 4/ added) and the organic phase, kerosene, was studied. A log-log plot of DBP concentration in the organic phase vs. that in the aqueous phase gave straight lines of slope 2 up to a certain point, above which the slope increased, indicating the existence of polymers higher than two in the organic phase. Addition of H/sub 3/PO/sub 4/ to the aqueous phase increased the DBP partition in the organic phase. The reactions are postulated to be (1)more » 2 DBP(aq) = (DBP)/sub 2/(org) and (2) (DBP)/sub 2/(org) + x H/sub 3/PO/sub 4/(aq (2 DBP - x H/sub 3/PO/sub 4/)(org). The data gave a distribution constant of 325 plus or minus 12 M/sup -10/ for reaction (1) and a formation constant of 0.31 plus or minus 0.03 for reaction (2), with x = 1.8 plus or minus 0.1.

  • In this study, adsorptions of uranyl ions from two different aqueous uranyl solutions by acrylamide-itaconic acid hydrogels were investigated by a spectroscopic method. The hydrogels were prepared by irradiating with {gamma}-radiation. In the experiment of uranyl ions adsorption, Type II adsorption was found. One gram of acrylamide-itaconic acid hydrogels sorbed 178-219 mg uranyl ions from the solutions of uranyl acetate, 42-76 mg uranyl ions from the aqueous solutions of uranyl nitrate, while acrylamide hydrogel did not sorb any uranyl ion. For the hydrogel containing 40 mg of itaconic acid and irradiated to 3.73 kGy, swelling of the hydrogels was observedmore » in water (1660%), in the aqueous solution of uranyl acetate (730%), and in the aqueous solution of uranyl nitrate (580%). Diffusions of water onto hydrogels were a non-Fickian type of diffusion, whereas diffusions of uranyl ions were a Fickian type of diffusion.« less
  • The influence of some cations and anions on the precipitate composition formed by the reaction of uranyl and errocyanide ions was studied by the amperometric titration method. It was shown that NH/sup +//sub 4/, Na/sup +/, Mg/ sup 2+/, Al/sup 3+/, Cr/sup 3+/, Ce/sup 3+/, VO/sup -//sub 3/, CrO/sup -//sub 4/, and Cl/sup -/ do not change the composition of uranyl ferrocyanide and do not interfere with the titration. Zn/sup 2+/, Cu/sup 2+/, Ni/sup 2+/, Pb/sup 2+/, Fe/ sup 3+/, Th/sup 4+/, MoO/sup 2-//sub 4/, PO/sup 3-//sub 4/ , and SO/sup 2-//sub 4/ ions interfere forming, in some cases, moremore » complicated compounds.
