Zirconium and hafnium are shown to be separable using 2-octanol (C8H18O) as an extractant. Zirconium basic
carbonate was dissolved using hydrochloric acids at concentrations ranging from 5 % to 20 %. Potassium
fluoride ...

Comparative solvent extraction studies of Zr and Hf were carried out from acidic chloride and potassium
fluoride solutions with 1 or 2-octanol as extractants. The extraction process was experimentally investigated
as a ...
