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 ... -
Automation of membrane based solvent extraction unit for Zr and Hf separation
(Elsevier, 2017)In recent years, research into metal ion solvent extraction using hollow fibre membranes has grown. Current studies generally use an analogue controlled experimental setup. Although the analogue system is sufficient for ... -
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 ... -
Separation of hafnium from zirconium using membrane based solvent extraction
(North-West University (South Africa)., 2022)The need for purified Zr and Hf has become imperative with the development of the nuclear industry. Solvent extraction (SX) processes, such as the TBP and MIBK processes have been successfully applied for the industrial ... -
Uranium recovery from simulated molybdenum-99 production residue using non-dispersive membrane based solvent extraction
(Elsevier, 2016)Commercial alkaline dissolution molybdenum-99 (99Mo) producers are currently not recovering enriched uranium (U) from 99Mo production waste which has a unique actinide and fission product composition. During the development ...
