Sažetak
Iron separation is described from liquid samples with a high concentration of ions that enables simple determination of 55Fe. One of the described methods consists of iron precipitation from a large volume seawater by sodium hydroxide and/or ammonium carbonate and separation from other elements (Ca, Sr, Cu, Mg, etc.) on a TRU column with 4M HCl or 8M HNO3. In the other procedure iron is separated directly from a mixture of seawater samples and HCl on TRU column. In both methods, the iron recovery is almost 100%. After separation, 55Fe is determined by counting with a liquid scintillation counter. The binding of Fe and Zn on TEVA, U/TEVA and TRU resins from seawater solutions of HCl and HNO3 depends on the type of the resin, concentration of acid and other ions. Iron and zinc can be separated from seawater on a U/TEVA column with 2M HCl.
