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.
