Separation of zirconium and hafnium by extraction as substituted ammonium chlorometallates (in German)

Journal Article · · Zeitschrift fuer Anorganische und Allgemeine Chemie
ZrdV) and Hf(IV) compounds form in hydrochloric acid chloroacids which cam be extracted from the inorganic phase by means of amines dissolved in organic solvents (e,g.) by means of tribenzyl amine in CHCl/sub 3/). The partition coefficient of zirconium is greater than that of hafnium; separation factors of 10 to 20 can be achieved. By this new method, Zr and Hf compounds having only low contents of the other metal below 0.01% Hf and Zr, respectively) were prepared in large scale by continuous and multistage separation techniques.
