The article represents the new chemically active natural minerals of Georgia – travertine and limestone. In this work, for the first time there have been studied adsorptive properties of the mentioned minerals in the process of aqueous solution purification from zinc ions. Materials under study are represented by unprocessed forms of travertine and limestone. Factors having an impact on sorption capacity of these minerals are analyzed based on the experiments.
The dependence of degree of adsorption and adsorptive capacity on adsorbent dosage, time contact, adsorbate concentration and solution pH has been studied. Optimum conditions for aqueous solution purification from zinc ions have been selected. Under the mentioned conditions, the maximum efficiency of degree of adsorption and adsorptive capacity has been 89,8% and 29 mg/g for travertine and 82% and 28 mg/g for limestone.
