2005-5-15 In strongly acidic solutions, molybdenyl cations (MoO 22+) occur. Extraction of the ABO–molybdenyl complex, (C 14 H 12 O 2 N 2) 2 MoO 2, from the acid medium is a selective method for the separation of molybdenum [1], [18], [19]. Thus, we examined ABO for the homogeneous liquid–liquid extraction of molybdenum.

The method for separation of molybdenum and tangsten was investigated on the basis of solution chemistry of both metal ions. Since molybdenum exists as the form of MoO 2 2+ in acidic solutions, molybdenum can be extracted with D2EHPA and LIX63. On the other hand, tangsten does not form such cationic species and then no extraction of tangsten ...
