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 NiII . 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.
