The inside of ion-exchanger has conventionally assumed to be a kind of homogeneous electrolyte solution. This assumption may inevitably lead to the result that the complexes UO2Cl53- and UO2Cl64- exist as sorbed species in the present uranyl-chloride

The separation of 12C and 13C isotopes by acid-base chromatography using an anion-exchange resin was investigated. In order to design the separation system, equilibria with respect to a carbon band were examined with reduction potential strength. Sim

Continuous bench-plant operation for about 4 months has resulted in the first recovery of 3%-enriched uranium by means of a chemical-exchange process. This confirms the reduced development time and uranium adsorption band stability predicted by mathe

An “inverse redox reaction”, in which ferrous, Fe(II), and titanyl, TiO(IV), ions are converted to ferric, Fe(III), and trivalent titanium, Ti(III), ions, was observed to occur within an anion-exchange resin in adsorption-desorption experiments,

Displacement chromatography, an alternate method to elution chromatography in terms of operation, is described. The principle of displacement is conveniently explained using the concept of an ‘addend’ which is regarded as a species essential to a
