Abstract
In this paper the ability of three natural zeolites from different localities (Vranjska banja-VB, Igroš-I and Baia Mare-BM deposits) to remove copper has been investigated. These three zeolites were subjected to the elementary analysis as well as XRDP and DTA/TG analysis due to complete characterization. Cation exchange capacity of VB, I and BM zeolites were 150.1, 169.2, and 176.5 meq/100g. The maximum adsorption capacity for the copper adsorption on VB, I and BM-zeolites were 7.75, 8.51, and 11.18 mg/g. Based on the obtained results the mathematical expression that describes correlation between the CEC and copper adsorption capacity has been developed. This linear dependance has been tested with the vast variety of experimental results. According to this expression it is possible to predict the copper adsorption capacity for different zeolites based only on their CEC value.
U radu su prikazani rezultati ispitivanja uklanjanja jona bakra primenom tri prirodna zeolita sa različitih lokaliteta (Vranjska banja-VB, Igroš-I i Baia Mare-BM). U cilju karakterizacije zeolita, izvršena su ispitivanja elementarnog sastava, kao i rentgenska (XRDP) i termijska analiza (DTA/TG). Kapaciteti katjonske izmene (CEC) ispitivanih zeolita VB, I i BM iznose 150,1, 169,2 i 176,5 meq/100g. Maksimalni adsorpcioni kapaciteti bakra na VB, I i BM zeolitima iznose 7,75, 8,51, i 11,18 mg/g. Na osnovu ostvarenih rezultata, dobijena je matematička zavisnost koja dobro opisuje vezu između vrednosti CEC i adsorpcionog kapaciteta za bakar. Ova lineralna zavisnost je testirana primenom različitih eksperimentalnih rezultata. Primenom ove zavisnosti moguće je da se predvidi vrednost adsorpcionog kapaciteta bakra na različitim zeolitima poznavanjem njegove CEC vrednosti. .
