Cesium Reduction

Chemical Formula: Cs
Present as:

Caesium or cesium is a chemical element with symbol Cs and atomic number 55. It is a soft, silvery-gold alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. It is the least electronegative element. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite, while the radioisotopes, especially caesium-137, a fission product, are extracted from waste produced by nuclear reactors.
The German chemist Robert Bunsen and physicist Gustav Kirchhoff discovered caesium in 1860 by the newly developed method of flame spectroscopy. The first small-scale applications for caesium were as a “getter” in vacuum tubes and in photoelectric cells. In 1967, acting on Einstein’s proof that the speed of light is the most constant dimension in the universe, the International System of Units used two specific wave counts from an emission spectrum of caesium-133 to co-define the second and the metre. Since then, caesium has been widely used in highly accurate atomic clocks.
Metallic cesium is highly reactive in both air and especially in water, reacting explosively, even temperatures as low as −116 °C (−177 °F). Cesium exclusively forms a monovalent cation. Almost all cesium salts are readily soluble in water.

SIR-600 has extremely high selectivity for cesium. Cesium is captured by molecular sieving in addition to in exchange. Hydrogen form cation resins such as CG8-H can also be used but their ability to remove cesium is limited by other ions in solution. In general when using SAC type resins to remove cesium it is necessary to remove all the other cations along with cesium.
