    Polymer-inorganic cation-exchangers containing zirconium hydrophosphate. Regeneration of uranium-loaded form
    (2018) Perlova, Olga; Dzyazko, Yulia; Perlova, Natalia; Ivanova, Inna; Palchik, Alexey
    It has been found that polymer-inorganic cation-exchangers, which contain nanoparticles of zirconium hydrophosphate, can be used many times for sorption of uranyl cations from diluted solutions. This is due to the possibility of practically complete regeneration of the loaded sorbents with diluted solutions of NaHCO3 or EDTA. The sample that includes the smallest embedded particles shows the highest regeneration rate.Встановлено, що органо-неорганічні катіоніти, що містять наночастинки гідрофосфату цирконію, можуть бути використані багаторазово для сорбції катіонів уранілу з розбавлених розчинів завдяки ефективній регенерації урранової форми цих сорбентів розбавленими розчинами NaHCO3 чи ЕДТА.

    Hybrid organic-inorganic nanocomposites for ion-exchange processes
    (2018) Dzyazko, Yulia; Ponomarova, Ludmyla
    Two types of composite ion-exchangers, which are based on strongly acidic gel-like cation-exchange resin and weakly acidic cation exchange resin have been obtained by modification with nanoparticles of zirconium hydrophosphate. Removal of the dye from deionized water and Ni(II) ions from water containing also hardness ions was studied under dynamic conditions. The composites show higher break-through capacity than that of the pristine resin.

    Sorption removal of uranium (VI) compounds with organic-inorganic ion-exchangers
    (2016) Perlova, Natalia; Perlova, Olga; Halutska, Iryna; Dzyazko, Yulia; Palchik, Alexey; Sazonova, Valentina
    Organic-inorganic composites based on ion exchange resins containing zirconium hydrophosphate (cation-exchanger) and hydrated zirconium dioxide (anion-exchanger) were applied to removal of soluble U(VI) compounds from modeling solutions. The advantages of the composites over the pristine resins are more significant sorption capacity, higher sorption rate and more facile regeneration.
