Sažetak
Natural zeolites are very 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 modifications. Usually, modifications change the type and quantity of the surface charge and therefore natural zeolites 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. One of the methods that change the sorption properties of natural zeolite clinoptilolite is the treatment in aqueous solutions containing Fe (III) at higher pH values. Table 1 indicates different methods with Fe (III) salts in aqueous media
