The distribution of macroquantities of hafnium and zirconium in nitric acid and tributylphosphate was studied. Extraction of hafnium is achieved with nitric acid concentration above 6 N; a high extraction of hafnium takes place at nitric acid concentrations over 9 N; the coefficient of hafnium distribution is slightly smaller than that of zirconium. Extraction of acid solutions of zirconium and hafnium at room temperature permits hydrolysis and polymerization, producing multi-complexes. An analysis was made of hafnium distribution as a function of concentration in solutions with 5.1 to 6.1 N acidity. (R.V.J.)
