Abstract

For the separation of the calcium and the strontium, a method of chromatography on paper has been proved using the radioactive indicators Ca-45 and Sr-89. The isopropanol-NH4CNS-water system was used. The variations of Rf and of the radioactive peak’s surface before and after the chromatogram's development were studied in connection with the amount of inactive elements present, from carrier-free solutions to mg-quantities of CaCl2 and SrCl2. The Rf only varies with the amount of carrier.
