Liquid-liquid extraction of Mo(VI) and V(V) by Primene JMT

Liquid-liquid extraction of Mo(VI) and V(V) by Primene JMT The extraction equilibrium of pentavalent vanadium and hexavalent molybdenum with a benzene solution of primary amine Primene JMT sulphate has been investigated. The comparison of the extraction of aqueous solutions containing the salts of the elements and the solutions containing the mixture of Mo(VI) and V(V) was carried out. The attention was directed to the pH 2–6 region in which the heptamolybdates and decavanadates in prevail aqueous phase and to the region ≈1M H 2 SO 4 which was suitable for the extraction separation of Mo(VI). The mechanism of extraction is discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Radioanalytical and Nuclear Chemistry Springer Journals

Abstract

The extraction equilibrium of pentavalent vanadium and hexavalent molybdenum with a benzene solution of primary amine Primene JMT sulphate has been investigated. The comparison of the extraction of aqueous solutions containing the salts of the elements and the solutions containing the mixture of Mo(VI) and V(V) was carried out. The attention was directed to the pH 2–6 region in which the heptamolybdates and decavanadates in prevail aqueous phase and to the region ≈1M H 2 SO 4 which was suitable for the extraction separation of Mo(VI). The mechanism of extraction is discussed.
