ABSTRACT of potassium and acetone [Marczenko 1972] was used for
determining the precise concentration of ions in the solution.
The ion adsorption of cobalt (2+) on the oxide sorbents with
different concentrations of the ions of Co2+ and pH has been B. Methods of studying the acid-base properties of the
experimentally studied. The acid-base model of adsorption, which sorbents
makes it possible to optimize the technological regimes of the
2+ The calculation of the constants of acid-base equilibria was
adsorption of Co on the anic sorbents (Co2O3, TiO2, Fe2O3, carried out by the method of the potentiometric titration. The
Fe3O4, SiO2 and other) has been proposed. The special feature of measurement of pH was conducted on the ionomer I -130.
model is calculation the double electrical layer (DEL) at the Titration was carried out by the solution KOH ( mole/L), in
oxide-solution border. an airtight thermostatically controlled cell (T=303 K). The
Keywords: double electrical layer, acid-base model, the ion mass of the hinge quantity of sorbents was 1 g on 50 ml
