Solvent Extraction of Calcium into Nitrobenzene by Using an Anionic LigandBased on Cobalt Bis(Dicarbollide) Anion with Covalently Bonded CMPO Function

摘要

From extraction experiments and γ-activity measurements, the exchange extraction constantcorresponding to the general equilibrium Ca2+(aq) + 2HL(nb) ? CaL2(nb) + 2H+(aq) taking place in the two–phase water–nitrobenzene (L– = anionic ligand based on cobalt
