A new process using a redox type of ion exchanger for cesium separation

I. A sorption-desorption-regeneration cycle with insoluble hexacyanoferrates of copper
  • K. Tanihara


A sorption-desorption-regeneration cycle composed of sorption of cesium on the sorbent in reduced state from strong nitric acid medium in the presence of an inhibitor such as hydrazinium salt, desorption of cesium by converting the spent sorbent into an oxidized state with a strong nitric acid eluent containing nitrous acid, and regeneration of the sorbent with a reducing agent such as hydrazinium salt was found to be possible with practically no loss of the sorbents when insoluble hexacyanoferrates of copper were used as redox type of ion exchangers.
