Sažetak
Natural zeolites are good sorbents and ion exchangers of heavy metal ions from aqueous solutions. In order to increase their sorption properties, scientists explore different methods of surface modification. Usually, modifications change the type and quantity of the surface charge and therefore natural zeolites can even become good adsorbents for nonpolar organic molecules. Some modifications entail the formation of a new porous solid phase on the inner and outer surface of the zeolitic particle (Han and Zou, 2009 ; Jeon and Beak, 2009 ; Dimirkou and Doula, 2008). One of the methods that change the ion exchange capacity of natural zeolite clinoptilolite for heavy metal ions is the treatment in aqueous solutions containing Fe (III) at pH ≥ 10 (Stanić and Kalajdžić, 2008).
