Abstract

A procedure of yttrium and strontium separation from calcium and other cations has been developed for rapid determination of Sr-90 in soil samples. The procedure involves yttrium, strontium and other cations bound on cation exchanger AMBERLITE IR-120, separtion of yttrium and strontium from other cations, e.g, potassium, calcium, sodium, barium, on anion exchangers AMBERLITE CG-400 or DOWEX AG Ix 8 with 0.25 mol l(-1) HNO3 in alcohol mixture as eluent, separation of yttrium from strontium on cation exchanger DOWEX 50 x 8 with 3 mol l(-1) HNO3, and determination of Sr-90 on the low-level gas-flow beta -counter and by Cherenkow counting on the liquid-scintillation counter. It has been shown that this procedure might be successfully applied in rapid determination of Sr-90, in a timesaving manner and without application of strong, concentrated acids. The method is appropriate for determination of the water soluble fraction of Sr-90 in different kinds of environmental samples (milk, water, wine, vegetables, etc.) with some modification of the sample preparation procedure.
