近年来稀碱金属铷、铯的研究与应用越来越引起人们的关注 ,因而对其分析方法也提出了更高的要求。根据有关文献对铷和铯的各种分离、分析方法的研究状况、进展及发展趋势进行了分析和评述。内容主要涉及铷、铯分离中的一些选择性较好的吸附试剂、萃取试剂的应用 ,及分析方法中适用于环境、生物和食品等样品中微量或痕量铷、铯分析的仪器分析方法 (包括原子吸收光谱法和原子发射光谱法等已经发展得较为完善且得到了广泛应用的经典方法 ,并介绍了一些近年来发展较快的仪器分析方法 ,包括电感耦合等离子体质谱法、X射线荧光光谱分析、离子选择性电极法等 )。引用文献 6 9篇。
In recent years, the research and application of dilute alkali metals rubidium and cesium have drawn more and more attention, so their analytical methods also put forward higher requirements. According to the relevant literature on the various separation of rubidium and cesium, analysis of the research status, progress and development trends were analyzed and commented. The contents mainly include some selective adsorbents in rubidium and cesium separation, the application of extraction reagents, and the instrumental analysis method of trace or trace rubidium and cesium analysis in the analysis methods for samples of environment, biology and food Including classical methods such as atomic absorption spectrometry and atomic emission spectrometry, which have been developed and widely used, and introduced some rapid instrument analysis methods in recent years, including inductively coupled plasma mass spectrometry, X-ray fluorescence Spectroscopy, ion-selective electrode method, etc.).
