A method for the separation of chemical elements in 8 groups suitable for gamma spectrometric analysis was developed. One group of elements is separated by distillation during dissolution of the sample. The other groups are obtained by means of short ion exchange columns coupled in series. An anion exchange column saturated with chloride ions separates chloride complexes, peroxides, and other anions from a 3 N HCl + 0.3% H/sub 2/O/sub 2/ sample solution. Some of the chloride complexes are eluted with 0.1 N HCl + 0.3% H/sub 2/O/sub 2/ and subsequently adsorbed as cations on a cation exchange column in hydrogen form. A few eluted elements which do not form cations in this case are found in the effluent. Elements passing the anion exchange column in chloride form without adsorbtion are separated from a H/sub 2/O solution as citrate complexes, hydroxides, cations, and hexametaphosphate complexes. This is done by coupling in series two anion exchange columns subsequently in citrate and hydroxide form and followed by a cation exchanger in sodium form. A mixed bed column ends the series. The behavior in the separation series of most elements forming gamma emitting isotopes with half lives exceeding 10 minutes on irradiation with thermal neutrons was studied. (auth)
