Automation of membrane based solvent extraction for Zr and Hf separation
(North-West University (South Africa), Potchefstroom Campus, 2015)In recent years, research into metal ion extraction using hollow fibre membranes has grown, focussing on the extraction of a wide range of metals including base, transition, and rare earth metals. This non dispersive solvent ... -
The selective extraction of Hf from Zr(Hf)Cl4(aq) using organophosphorous derivatives
(North-West University (South Africa), 2015)While traditional solvent extraction (SX) separations of Zr and Hf focus on the preferential extraction of Zr (majority solute) from Hf (minority solute), the aim of this study was to ascertain whether the selective ... -
Selective membrane based solvent extraction of Hf from a (NH4)3Zr(Hf)F7 solution
(North-West University (South Africa), Potchefstroom Campus, 2016)Zr and Hf, which co-exist in nature, have similar chemical properties, except for their Zr and Hf, which co-exist in nature, have similar chemical properties, except for their absorbance of neutrons which implies that Zr ... -
The speciation and solvent extraction of zirconium and hafnium : a computational and experimental approach
(North-West University (South Africa), Potchefstroom Campus, 2015)Zirconium and hafnium have important applications within the nuclear industry, where zirconium is used to clad the uranium fuel rod tubes that are used during nuclear reactions and hafnium is used in the control rods which ...
