EXTRACTION OF HAFNIUM BY TRIBUTYL PHOSPHATE (in Russian)

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.)
