A Study of the Separation of Hafnium and Zirconium Using TTA,

Abstract

The two-phase equilibrium of Zr(+4) between a dilute acid aqueous phase and the thenoyltrifluoroacetone (TTA) chelate of zirconium in benzene was investigated by R. E. Connick and W. H. McVey UCRL-101 (AECD-2272). Their studies were essentially all done in perchloric acid and gave information on the principal species of zirconium found in the aqueous phase, the specie extracting into the benzene and equilibrium constants for the reaction in 2M HClO4. In addition they investigated the effect on the extraction coefficients of various substances known to complex zirconium in aqueous solution, in particular bisulphate and fluoride ions. JG P.4
