Strontium-90 may be determined by beta-counting its yttrium-90 daughter following separation by ion-chromatography, using a three column system comprising a chelating concentrator column, a cation-exchange column and an anion-exchange separator column. The column system has previously been applied to the determination of strontium-90 in water and urine samples. The applicability of the system to the analysis of milk is hampered by the large concentrations of calcium present, which significantly… Expand
A Simple Method to Screen for Radiostrontium in Water by Ion Exchange Chromatography
TLDR
A method to analyze 89Sr and 90Sr in water has been developed using gradient elution with dilute hydrochloric acid and cation exchange resin, followed by carbonate precipitation, found to be simple, exhibiting high recovery, reduced use of hazardous chemicals, and lower cost compared to other current methods.
