The kinetics of sorption of ions of indium, iron and zinc on a modified montmorillonite


The obtained integral kinetic curves of adsorption of ions of indium and iron (III) from model solutions on a modified di(2-ethyl-hexyl)phosphoric sour the montmorillonite Metosol. It is shown that the kinetics of adsorption can be reliably described by models of pseudofirst and pseudosecond order. Installed mode of adsorption of metal ions on the reactant Metosol. For ions In3+ are the rate constants of external and internal diffusion on the reagent Metosol more than for Fe3+, which leads to the possibility of its use of for selective adsorption of indium from the complex composition of technological solutions of zinc production.
Key words: montmorillonite, aluminosilicates, indium, iron, zinc, sorption, intercalation.
