“…An attempt is made to compare the uranium distribution on impregnated activated carbons wiib bulk liquid extraction. However, as discussed elsewhere (30), an associated study of the physical and thermodynamic characteristics of the stationary phase (TBP) on ibe support material (activated carbon) is needed for a rigorous comparison of the behaviour of the stationary phase in extraction chromatography wiib the equivalent phenomena in bulk liquid-liquid extraction, Moreover, conformational structure and stereochemistry of the stationary phase reagent and porous structure of the support have to be fully known.…”
