Sorption properties of hybrid organic-silica material towards , and radionuclides

Hybrid organic-silica material modified by amino groups has been investigated as adsorbent of radionuclides   90 Sr ,   90 Y and   137 Cs from aqueous solutions. The sorption ability of the organic-silica material in the pH range of 2–9 with thermostating is studied by static sorption method. Analys...

Description
Summary:Hybrid organic-silica material modified by amino groups has been investigated as adsorbent of radionuclides   90 Sr ,   90 Y and   137 Cs from aqueous solutions. The sorption ability of the organic-silica material in the pH range of 2–9 with thermostating is studied by static sorption method. Analysis of sorption kinetic curves of radionuclides for aminoxerogel has shown that sorption equilibrium is established in 3–3.5 h. It is shown that the mechanisms of radionuclides sorption on the organic-silica material are combined by the complex formation and ion-exchange mechanism. The amino containing organic-silica material can be recommended for the cleaning of surfaces and purification of water solutions contaminated with   90 Sr and   90 Y .
