Abstract

We studied the use of an extraction chromatography for determination of 90Sr in contaminated water samples. The aim of our work was to compare selected products from the point of view of the strontium chemical yields and analysis time. Three commercial products, 3M Empore™ Strontium Rad Disk, AnaLig® Sr-01 gel, Sr®Resin, and two classical methods, liquid–liquid extraction with tributhylphosphate and carbonate co-precipitation, were tested for the separation of 90Sr. The water sample from nuclear power plant A1 Jaslovske Bohunice was used for radiochemical analysis of 90Sr volume activity. Samples were traced with 85Sr to monitor strontium chemical recovery and counted either by Cerenkov counting on TRI CARB 2900 TR liquid scintillation counter or low level alpha–beta proportional counter.
