Vanadium and arsenic eliminations from an alkaline leaching solution o
f spent VKCs catalysts were studied. To this end, several commercial r
esins or polymers synthesized in the laboratory were evaluated in a so
lid-liquid batch extraction. Conditions for an effective extraction of
vanadium and arsenic were determined. An extraction process, using a
glass column, is described for the recovery of the vanadium. The elimi
nation of arsenic by precipitation is proposed.
