Abstract:
The present research set a goal of study of applicability of the expanded perlite obtained on the basis of perlite – natural mineral of Georgia, from adsorption removal of Fe3+ ions from aqueous solution.
Adsorptive characteristics of the expanded perlite have been studied in the process of aqueous solution purification from trivalent iron ions in regard to adsorbent dosage, contact time, adsorbate concentration and solution pH. The dependence of adsorption degree and adsorptive capacity of the expanded perlite from the above-mentioned parameters have been uncovered.
Optimum conditions of Fe3+ ions adsorption have been established. Maximum values of adsorption degree and adsorptive capacity were equal to 89% and 4,45mg/g, respectively.
Keywords:
Expanded perlite; Adsorption; Adsorption degree; Adsorptive capacity
