锶的分离检测方法研究进展

Development of Separation Procedures for the Determination of Strontium

锶是高放废水中主要的释热裂变产物之一,同时也是重要的战略资源。从卤水矿物资源或废水以及环境水中分离提取锶,具有重要现实意义。对锶进行有效的分离检测是首要解决的问题。文章综述了多种水样品中锶含量测定所涉及分离与检测方法的研究进展,包括预处理、预富集以及沉淀、离子交换、溶剂萃取和萃取色谱等技术,并比较了不同方法在选择性、时效性和适用性上的差异,探讨了锶分离检测方法研究的发展方向。

Strontium is one of the main fission heating elementals in high- level radioactive waste water,which is an important strategic resource. It also has valuable practical significance for extraction of strontium from brine,waste water and environmental waters. Therefore,it is the first problem to resolve the effective separation and determination of strontium for this purpose. In the paper,the research progress of methodologies involved in the separation and determination of strontium in various water samples were reviewed,including pre- treatment,pre- concentration,precipitation,ion exchange,solvent extraction and extraction chromatography,etc. The selectivity,timeliness and applicability of the methodologies were compared and the prospects in the separation and determination for strontium were also discussed.
