Adsorption behavior and kinetics of exchange of Co2+ and Eu3+ ions on polymer composite ion exchanger
Equilibrium and kinetics of exchange of Co-60 and Eu152+154 radionuclides on hydrous titanium oxide incorporated in polyacrylonitrile, TiO-OH-PAN, were studied. The capacities of TiO-OH-PAN for Co-60 and Eu152+154 were found to be 2.35 and 2.69 meq/g respectively. Freundlich and Langmiur isotherms were investigated. The validity of the Langmuir isotherm over the specified concentration range indicates monolayer coverage of the surface of TiO-OH-PAN by cobalt and europium. Sorption data was treated with the Dubinin-Radushkevich equation. The results indicated that hydrous titanium oxide incorporated in polyacrylonitrile can be considered as a promising material for removal of cobalt and europium ions from aqueous solution.
