Notes:
Studies of the solvent extraction of cobalt and nickel nitrates from aqueous solution would add to the fundamental knowledge of extraction of metal salts. In experiments performed to determine the extractibility of these metals as nitrates from aqueous solutions by organic solvents, normal butanol was found to be the best solvent and gave equilibrium distribution coefficients K for cobalt or nickel nitrate of about 0.3. The presence of nitric acid tended to decrease these at high metal concentrations.In mixtures of the two metals the K value of either metal was found to depend on the total metal concentration. Low separation factors of about 1.3 were obtained. Very high K values of over 5 were obtained for the equilibrium extraction of the nitric acid in the presence of the metal nitrates by the n-butanol an indication of commercial possibilities.
