Abstract  

A simple chromatographic method to separate carrier-free60Co and54Mn, produced in the neutron irradiation of Fe2O3, has been developed. The separation of carrier-free60Co was performed in the displacement mode using DTPA as a displacer and H+ as a barrier ion; carrier-free54Mn was separated in the form of54MnO 4 from55+59Fe in the elution mode using HNO3 as an eluent.

Abstract  

Radioactive impurities of153,159Gd were determined as160Tb and154Eu by pressurized displacement chromatography. They were separated by pressurized elution chromatography with α-hydroxyisobutyric acid-ascorbic acid system. As the result, radiochemically pure153,159Gd was obtained.
