Copper Ions Adsorption from Aqueous Solution Using Perlite

Abstract

There were explored adsorption properties of natural mineral of Georgia-perlite in the treatment process of aqueoussolution of copper.There was studied the dependence of Cu (II) adsorption degree from adsorbent dosage, contact time and solution pH on both initial (not-expanded) and foamed (expanded) perlite.Under optimum conditions (pH = 1.9, contact time 1 h and adsorbent amount 5 g) adsorption capacity and adsorptiondegree of copper were equal to 11,2mg/g and 94%.It is showed that foamed perlite manifests perfect adsorption properties for copper removal from aqueous solution and it can be recommended as a potential adsorbent in the mentioned process.
