  Efficient separation of vanadium from chromium by a novel …

  2015315 · Furthermore, vanadium and chromium are a pair of adjacent transition metals and co-exist in nature. It is not an easy task for the separation of vanadium from chromium due to their similarly physicochemical properties. In the past decades, the separation of V (V) from Cr (VI) has drawn considerable attention.
