摘要
Molybdenum and rhenium may be co-extracted from acidic media by a mixture of trioctylamine (3.2-4.5%) and Aliquat 336 (0.5-1.8%) in kerosene/5% iso-octanol. Molybdenum can be selectively stripped by ammonia or ammonium salts to give an aqueous phase containing 60 g/l Mo and 0.01 g/l Re. Rhenium may then be stripped from the resulting organic phase with 8 M nitric acid to give an aqueous solution containing 7 g/l Re and 0.15 g/l Mo. © 1979.
