title: Anion-exchange preparation of a (232)U radiotracer for alpha-particle liquid scintillation counting.
abstract: Daughter product ingrowths, which could act as analytical interferences, are removed from (232)U(VI) stock solutions prior to use as an alpha-particle emitting radiotracer in conjunction with detection by liquid scintillation counting. The preparative benchtop separation procedure employs elution with HCl through a BioRad AG1-X8 anion-exchange resin column, and fraction collection. The importance of the separation of the (232)U isotope from daughter products, characterized by high recovery, is illustrated by liquid scintillation energy spectra. Rapid ingrowth in the purified fraction also limits the period of time after purification in which the radiotracer is usable.
