抄録

Photoreductive stripping of V in a liquid-liquid extraction process for separation of V and Mo was investigated. A halogen lamp or a low-pressure mercury lamp was used as a light source and 2-propanol was used as an OH radical scavenger. The pentavalent V was photoreduced to V(IV) and stripped selectively from tri-n-octylmethylammonium chloride (TOMAC)/benzene organic phase into HCl-NaCl aqueous phase. The separation factor of 170–250 was obtained by a single extraction-stripping process. The equilibrium relationship in the course of the stripping process was also investigated. The scheme of photoreductive stripping of V was formulated, taking the photoreduction in aqueous phase into consideration.
