Multisyringe flow injection analysis of stable and radioactive strontium in samples of environmental interest
1Department of Chemistry, University of the Balearic Islands, Palma E-07122, Spain.
Abstract:
A multisyringe flow injection (MSFIA) method for the determination of stable and radioactive strontium, using a solid phase resin (Sr-Resin), has been developed. Strontium concentrations are determined by atomic emission spectroscopy and by a low background proportional counter. The method has been applied to different samples (water, milk and soil) of environmental interest. The LLD of the stable and radioactive Sr were 10 microg/l and 0.01 Bq, respectively. The standard deviation of the separation procedure is 2% (n=10).
