Computational chemistry study of zirconium monomers in low acid concentration aqueous solutions
Jansen van Vuuren, D.B.; Krieg, H.M.; Van Sittert, C.G.C.E. (IOP Publishing, 2018)Zirconium and hafnium have to be separated prior to their use in nuclear energy reactors. Therefore, a lot of research has been done on the solvent extraction of zirconium. However, most of this research involved screening ... -
The effect of molar ratio and flow velocity on the surface area required for pertraction of a Zr/Hf mixture
Malan, D.; Van der Westhuizen, D.J.; Neomagus, H.W.J.P.; Krieg, H.M. (IOP, 2019)Zirconium (Zr) and hafnium (Hf) need to be separated before being used in nuclear applications. Equilibria data have shown that Hf can be selectively extracted over Zr from a sulphate medium using organophosphorus ...
