Sažetak
In this study, a natural zeolite (NZ) sample has been used in preparation of iron modified zeolite (IMZ). The uptake of cadmium ions on NZ and IMZ has been examined. The experimental results have showed that the capacity of IMZ is four times higher than that of NZ. Almost complete Cd removal is achieved at the initial Cd concentration of 232.69 mg/l, which imposes IMZ as a good sorbent material. The balance between outgoing Na, K, Ca, Mg and ingoing Cd ions shows an almost complete stoichiometric relation, indicating ion exchange as the main process responsible for Cd uptake on IMZ.
