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.
