SEPARATION OF VANADIUM, ZIRCONIUM, TITANIUM, MOLYBDENUM, TUNGSTEN, AND COLUMBIUM BY ELUTION DEVELOPMENT ION EXCHANGE CHROMATOGRAPHY
Abstract
The elution behavior of vanadium, zirconium, titanium, molybdenum, tungsten, and columbium was studied at various hydrolfluoric acid concentrations employing a strong base anion exchange resin. The results of this study were used to establish appropriate separation schemes. Coupled columns were employed for the separation of the complete group. Simple columns were used for less complicated mixtures. Vanadium, zirconium, titanium, and molybdenum were eluted with appropriate hydrofluoric acid solutions. In this way, interference from large amounts of columbium was avoided. An 'interval' equation defining the desired volume interval between successively eluting solutes is offered for calculating the column length required for a particular separation. This equation is especially useful for determining the extent to which a column must be lengthened when overlapping occurs due to high column loading.
