AbstractAbstract
[en] Technetium, as 99Tc, was rapidly concentrated from large sample volumes (> 500 cm3) by use of an anion exchange column after removal of ruthenium isotopes by precipitation. The bulk of the technetium can be removed from the resin by elution with sodium thiocyanate followed by further concentration by extraction with butan-2-one. Evaporation of solvent onto a planchette followed by measurement of emitted beta radiation can determine technetium levels. Method is capable of removing between 10-15 and 10-6g of technetium from 500 cm3 of water. (author)
