Sažetak
Procedures of isolation and determination of 90Sr in liquid samples have been described, with cation and anion exchangers used in isolation. Strontium, yttrium and other cations bind to the cation exchanger and are eluted from the column by means of nitric acid. Separation of yttrium and strontium from other cations is carried out on the columns filled with strong base anion exchangers in nitrate form with alcoholic solutions of nitric acid. Such method of isolation enables the determination of 90Sr through yttrium on a low-level gas flow ?,?-counter, as well as through strontium on a low-level liquid scintillation counter by means of Cherenkov counting. Such developed procedures have been tested by the determination of 90Sr in water, wine, medium radioactive liquid waste samples, milk and clover samples. For the purpose of comparison, the determination has also been carried out by the standard method. It has been showed that the developed procedures might produce a high efficiency in strontium isolation and a satisfactory accuracy of determination.
