Projekat:
Implementacija savremenijih tehničko-tehnoloških i ekoloških rešenja u postojećim proizvodnim sistemima Rudnika Bakra Bor i Rudnika Bakra Majdanpek (MPNTR - 33007)

Ključne reči: zeolit; adsorpcioni kapacitet; baker; matematička zavisnost
Sažetak
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.
