A quick, automated and portable system for the separation and determination of radiostrontium in aqueous samples, using Sr-resin and multi sequential flow injection analysis, has been developed. The concentrations of radioactive strontium were determined by flow scintillation counting, allowing for on-line and also on-site determination. The proposed system can determine radioactive strontium at industrial relevant levels without further modification using overall analysis time of less than 10 min per aqueous sample. The limit of the detection is 320 fg·g (1.7 Bq/g).
已经开发出一种快速、自动化且便携的系统，该系统使用锶树脂和多序贯流动注射分析来分离和测定水样中的放射性锶。通过流动闪烁计数法测定放射性锶的浓度，可实现在线和现场测定。所提出的系统无需进一步修改，即可在工业相关水平下测定放射性锶，每个水样的总分析时间不到10分钟。检测限为320 fg·g（1.7 Bq/g）。
