SOLVENT EXTRACTION OF MOLYBDENUM. Open

The extraction constant for the reaction of molybdic acid and the neutral ligand was estimated to be 100,000. The kinetics of extraction Mo (VI) with LIX63, 8 hydroxyquinoline, 8 hydroxyquinaldine, and Kelex 100 were studied in this work. In all cases, except 8 hydroxyquinoline, the rate determining step of the reaction involves
