Modeling of dissolution of chromium (III)
and copper oxides in an acidic environment
Abstract
An experimental study was made of the
dissolution of chromium(III) and copper oxides in acidic media. Based on
experimental studies of the effect of acids, pH and the concentration of anions
on the dissolution rate of oxides, the nature of the limiting stage is
determined, which consists in the formation of surface compounds (depending on the
pH value): and their subsequent transition to electrolyte solution.
Key words: chromium(III) oxide, copper
oxide, dissolution kinetics, dissolution mechanism, dissolution process.
