A study of isotope-effects in the high-resolution 195Pt NMR spectra of octahedral complexes of the type [PtCl6-n(OH)n]2-, n = 0-6, in water
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: The high-resolution 195Pt NMR signals (128.8 MHz) of most of the octahedral mixed-ligand Pt(IV) complexes in the series [PtCl6-n(OH)n]2-, n = 0-6, have been recorded in aqueous solutions at 293 K. These ...
Chemical speciation of RhIII complexes in acidic, halide-rich media by means of 103Rh NMR spectroscopy : the importance of speciation in the selective separation and recovery of rhodium
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: In this thesis, the recovery of RhIII from both synthetically prepared and authentic industrial PGM-containing solutions was systematically investigated via organic precipitation methods using several ...
