Abstract
Abstract— Adsorption properties of Georgian expanded
perlite prepared on the basis of perlite – natural mineral of
Georgia in the process of aqueous solution purification from
bivalent iron ionswere investigated for the first time in the
work. The dependences of adsorption degree and volume
capacity on change of solution pH, adsorbent dosage, contact
time and adsorbate concentration were studied. Tests were
mainly conductedunder dynamic and static conditions.
Optimum conditions for Fe2+ adsorption on expanded perlite
have been determined. Maximal efficiency of iron adsorption
degree was equal to 91%, and volume capacity – 1.82 mg/g.
Expanded perlite shows excellent adsorption properties in the
process of iron removal from aqueous solution.
