Title: Behaviors of acrylamide/itaconic acid hydrogels in uptake of uranyl ions from aqueous solutions

Abstract

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 observed 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.

  • In this study, acrylamide-maleic acid (AAm/MA) hydrogels in the form of rod have been prepared by {gamma}-radiation. They have been used for adsorption of some heavy metal ions such as uranium, iron, and copper. For the hydrogel containing 40 mg of maleic acid and irradiated at 3.73 kGy, maximum and minimum swellings in the aqueous solutions of the heavy metal ions have been observed with water (1480%) and the aqueous solution of iron(III) nitrate (410%), respectively. Diffusions of water and heavy metal ions onto hydrogels have been found to be of the non-Fickian type of diffusion. In experiments of uranylmore » ions adsorption, Type II adsorption has been found. One gram of AAa/MA hydrogels sorbed 14-86 mg uranyl ions from solutions of uranyl acetate, 14-90 mg uranyl ions from solutions of uranyl nitrate, 16-39 mg iron ions from solutions of iron(IV) nitrate, and 28-81 mg copper ions from solutions of copper acetate, while acrylamide hydrogel did not sorb any heavy metals ions.« 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.

  • The interaction of polyvalent cations with polyions is well known to strongly alter the rheological properties of hydrolyzed polyacrylamide used in the tertiary oil recovery process. The influences of divalent cations have already been studied but the role played by the presence of small quantities of aluminum ions has never been investigated. In a first part of this paper, the authors discuss results of a /sup 27/Al NMR study of the binding of Al ions on acrylic acid - acrylamide electrostatic model. The second part deals with the phase diagrams, physical gelation and precipitation phenomenon, for different copolymer compositions andmore » under various conditions of concentrations and pH.« less
