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).
已开发出一种使用固相树脂（锶树脂）测定稳定态和放射性锶的多注射器流动注射分析（MSFIA）方法。通过原子发射光谱法和低本底比例计数器测定锶浓度。该方法已应用于具有环境意义的不同样品（水、牛奶和土壤）。稳定态和放射性锶的检测限分别为10微克/升和0.01贝克勒尔。分离过程的标准偏差为2%（n = 10）。
