Abstract

Sorption behavior of strontium ions on manganese oxides obtained by sol–gel technique reduction of KMnO₄ by different reagents (H₂O₂, MnCl₂ and polyvinyl alcohol) was studied. Sorption capacity of the most effective sorbent reaches 200 mg g⁻¹ and distribution coefficient K_d (⁸⁵Sr)—3.67 × 10⁵ cm³ g⁻¹. Ion-exchange and chemisorption mechanism of strontium ions removal by manganese oxides were confirmed by means XRD, FT-IR, N₂ adsorption–desorption and SEM–EDX methods. The obtained sorbents are promising for liquid radioactive water treatment from strontium radionuclides.
