ABSTRACT:
The isotopes of zirconium can be partially or completely separated by loading an essentially anhydrous alcoholic solution of an ionic compound of zirconium onto a cationic exchange resin with pentavalent phosphorus derived active groups which serves as the stationary phase of a chromatograph, eluting the compound with an essentially anhydrous alcoholic solution of hydrogen chloride and collecting distinct elution volumes representative of each isotope. In a preferred embodiment, the active groups of the cation exchange resin are derived from di-2-ethylhexyl phosphoric acid, tri-n-octyl phosphine oxide or tributyl phosphate and the chromatograph is of a type, such as a continuous annular chromatograph that it can be operated in a continuous steady state manner.
