Preparation of Amidoxime-Fiber Adsorbents Based on Poly(Methacrylonitrile) for Recovery of Uranium from Seawater∗ [PDF]
Separation Science and Technology, 1994 Abstract Polymerization of methacrylonitrile was performed with anionic initiators as reported in the literature. The molecular weight of the polymer produced using BuLi as initiator at 0 ± 2°C was on the order of 105. Maximum conversion was 97% with BuLi initiator.

The uptake of radionuclides from aqueous solution by poly(amidoxime) modified reduced graphene oxide
Chemical Engineering Journal, 2014Abstract Poly(amidoxime) (PAO) was grafted on the surface of reduced graphene oxide (rGO) via an in situ polymerization reaction to fabricate poly(amidoxime) grafted graphene (PAO-g-rGO) complexes. The as-prepared composites exhibited improved hydrophilicity and were characterized by scanning electron microscopy (SEM), Raman spectroscopy, X-ray ...

Seawater reserves about 4.5 billion tons of uranium, if properly extracted, could be a sustainable green energy resource for hundreds of years, alternating its limited terrestrial ore and reducing the CO2 emitted from fossil fuels. The current seawater uranium adsorbents suffer neither economically viable nor adsorption efficiency, requiring more ...

Synthesis of zirconium poly‐O‐amidoximes
Journal of Polymer Science: Polymer Chemistry Edition, 1974AbstractSynthesis of zirconium poly‐O‐amidoximes was affected by using both interfacial and aqueous solution techniques. Reaction is rapid. The yield for the synthesis of analogous titanium product is Cp2ZrCl2 > Cp2TiCl2 which is consistent with that predicted by the hard‐soft acid–base theory.

The extraction of uranium from seawater by poly(amidoxime)/poly(hydroxamic acid) resins and fibre
Reactive Polymers, Ion Exchangers, Sorbents, 1983Abstract The uranium concentration in seawater is 3 μg/l with an estimated 5 × 109 tonnes of uranium in the oceans, in solution as the tricarbonato complex. Any extraction process will encounter the problems attendant on this high dilution, the only feasible methods currently being ion exchange on chelating resins or sorption onto inorganic materials.
