Item Copper ions adsorption from aqueous solution using perlite(International Journal of Ney Technologg and Research, 2020) Ioseliani, D.K.; Balarjishvili, G.I.; Kalabegashvili, N.G.; Samkharadze, L.O.; Nonikashvili, N.U.; Mikadze, I.I.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.Item Copper Ions Adsorption from Aqueous Solution Using Perlite(International Journal of New Technology and Research (IJNTR), 2020-07) Ioseliani, D.K.; Balarjishvili, G.I.; Kalabegashvili, N.G.; Samkharadze, L.O.; Nonikashvili, N.U.; Mikadze, I.I.There were explored adsorption properties of natural mineral of Georgia– perlite in the treatment process of aqueoussolution of copper.

Dependence of degree of adsorbents’ adsorption on the composition of adsorbent, mutual ratio, mechanoactivation and experiment duration was studied. It was shown that in the mentioned process, adsorbent brucite:mordenite at the ratio of 1:1 is the best adsorbent taking into account practical and economic factors. This adsorbent purified a water of Kazretula River by 100 %, while modeled solution similar to the acidic quarry water were purified from copper by 93% and from iron by 87%.Item Use of plant raw materials for purifications of industrial waste waters from copper and iron ions(International journal of advanced research, 2019-05) Kalabegashvili, N.G.; Balarjishvili, G.I.; Samkharadze, L.O.; Ioseliani, D.K.; Mikadze, I.I.; Tsikarishvili, R.P.
