Separation of vanadium ions from the post-leaching solution of spent vanadium catalyst
Spent V catalyst from H2SO4 prodn. was disintegrated and leached with KOH soln. The leachate was either treated with NH4Cl or BaCl2 to ppt. the resp. vanadates or contacted with an anion-exchange resin to absorb the V ions. The degree of V sepn. was about 90% (pptn.) or near 100% (anion exchange).
