Abstract
Adsorption integral kinetic curves of indium and iron(III) ions were obtained from model solutions on a montmorillonite Metosol modified with di(2-ethylhexyl)phosphoric acid. The adsorption kinetics can be reliably described with pseudofirst and pseudosecond order models. Adsorption of metal ions on a Metosol reagent occurs in a mixed diffusion mode. The rate constants of external and internal diffusion on the Metosol reagent are greater for In3+ ions than those for Fe3+ one, so that it can be used for the selective sorption of indium from complex technological solutions in zinc production.
