Theory of Chromatographic Separation of Isotopes
TLDR
A comprehensive expression which describes the concentration profile is derived for two-isotope systems in any kind of chromatography, without or with a counterflow.Abstract:
A fundamental equation for chromatography is derived starting from a very simple concept that the chromatographic movement of species can be expressed as the sum of the movement caused by the external force and the movement caused by the internal concentration gradient and its transformations into appropriate forms are discussed in the cases of ion exchange (or gas) chromatography and ionic migration, without or with a counterflow. By solving the fundamental equation, making appropriate assumptions, a comprehensive expression which describes the concentration profile is derived for two-isotope systems in any kind of chromatography.read more

Factors affecting single-stage separation coefficients and profile of the chromatogram in uranium isotope enrichment by cation-exchange chromatography using uranyl-carboxylate complexes
TL;DR: In this paper, the single-stage separation coefficient, e, and the slope coefficient, k, which is one of the important factors determining the isotopic fraction profile of the isotope-enriched and -depleted zones of the chromatogram, were evaluated and the influence of several experimental parameters on the e and k values was discussed.
