Properties of the Alkali Metals and Implications for Cesium Selectivity

PROPERTIES OF THE ALKALI METALS AND IMPLICATIONS FOR CESIUM SELECTIVITY 

Separation of alkali metals from one another constitutes one of the most challenging separation problems that one may encounter. Compared with other families of metal ions, the alkali metals do not offer easily exploitable redox chemistry, directional bonding, or covalent interactions. Practically 

The radioactive element Fr, whose longest lived isotope, Fr, has a half-life of only 21.8 min. [123], presents experimental difficulties and is consequently poorly characterized chemically. It will be little mentioned again other than to point out here that strategies for separating Cs ion may
