Abstract:
Adsorptive capacities of expanded perlite, prepared on the basis of natural mineral of Georgia – perlite, in the process of aqueous solution purification from Zn (II) ions, have been first studied in the work. The dependencies of adsorption degree and volume capacity on adsorbent dosage, contact time, adsorbate concentration and pH of solution medium have been studied. Experiments have been conducted under dynamic conditions.
Optimum conditions of Zn(II) ion adsorption have been established. Maximal efficiency of adsorption degree under these conditions was equal to 93,6, while volume capacity – 3,7 mg/g.
Keywords:
Expanded Perlite; Zinc Ions; Adsorption; Adsorption Degree.
