Abstract: A paper chromatographic separation of Cr, Mn, Co, Fe and Ni using a double run development in two solvent systems was developed. One strip of paper was developed with solvent system pyridine — water (60 : 40) and after complete pyridine removal in the opposite direction with acetone—7 N-HC1 (90 : 10). Optimal distances of chromatographic spots for three possible configurations were computed for given total lenght of run. The validity of the method was proved by separation of radioisotopes ⁵1Cr, ⁶⁴Mn, ⁶⁰Co, ⁶⁹Fe and Ni^II . and it was found suitable for separation and quantitative determination of these radioisotopes with carriers or carrier-free respectively. The advantage of the presented procedure is in the separation of Cr, Mn, Co, Fe, and Ni on one paper strip suitable for radiometric evaluation.
