Abstract	Provedena je kemijska modifikacija prirodnog zeolita porijeklom iz Vranjske Banje, Srbija s vodenom otopinom Fe(NO 3 ) 3 u acetatnom puferu pri pH = 3,6 te s otopinama NaOH i NaNO 3 . Za detaljnu komparativnu mineralošku i fizikalno-kemijsku karakterizaciju prirodnog i Fe(III)-modificiranog zeolita korišteni su klasična kemijska analiza, kisela i bazična svojstva određena Bohemovom metodom, kemijsko ponašanje pri različitim pH o vrijednostima, zeta potencijal pri različitim pH o vrijednostima, specifična površina, rendgenska difrakcijska analiza praškastog uzorka (XRPD), pretražna elektronska mikroskopija s energijsko disperzivnom rendgenskom spektroskopijom (SEM-EDS), infracrvena spektroskopija s Fourierovom transformacijom (FTIR) kao i termogravimetrijska analiza (TG-DTG) korišteni su. Modifikacijom nije došlo do promjena u strukturi i mineraloškom sastavu zeolita, a povećao se volumen pora i količina natrijevih iona kao rezultat ionske izmjene i neutralizacije negativnog naboja nastalog tijekom modifikacije. Dobiveni Fe(III)-modificirani zeolit pokazao je gotovo dvostruko veći kapacitet vezivanja Hg(II) u odnosu na prirodni, što opravdava metodu modifikacije prirodnog zeolita.
Abstract (english)	Chemical modification of natural zeolite originated from the Vranjska Banja, Serbia deposit has been performed with the aqueous solution of Fe(NO 3 ) 3 at pH = 3.6 and with NaOH and NaNO 3 solutions. For detailed comparative mineralogical and physico-chemical characterization of natural and Fe(III)-modified zeolite the chemical analysis, acid and basic properties determined by Bohem’s method, chemical behavior at different pH o values, zeta potential, specific surface area, X-ray powder diffraction (XRPD), scanning electron microscopy with energy-dispersive X-ray analysis (SEM- EDS), Fourier transform infrared spectroscopy (FTIR), as well as thermogravimetry (TG-DTG) were used. The modification did not cause changes in the structure and mineralogical composition of the zeolite, but it increased the pore volume and the amount of sodium as a result of ion exchange and neutralization of the negative charge created during the modification. The obtained Fe(III)-modified zeolite has shown almost twice higher sorption capacity for Hg(II) compared to natural one, which justifies the method of modification of natural zeolite.
