Validation of rapid methods for the determination of radiostrontium in milk

A rapid method of 89Sr and 90Sr comprising ion chromatography for preconcentration and Sr extraction chromatography for separation of Sr from Ca, Ba and Y was validated with spiked milk samples. An 89Sr/ 90Sr activity ratio of up to 12 showed the relative bias was within ±20%. The separation time of...

Summary:A rapid method of 89Sr and 90Sr comprising ion chromatography for preconcentration and Sr extraction chromatography for separation of Sr from Ca, Ba and Y was validated with spiked milk samples. An 89Sr/ 90Sr activity ratio of up to 12 showed the relative bias was within ±20%. The separation time of Sr was 7 h and the chemical recovery of Sr ranged from 80% to 95%. The detection limit for 500 mL milk and 90 min counting time was 0.1 Bq L −1.
