Abstract
Frozen solution samples were made from gold chloride and KAu(CN)2 solvated with TBP/xylene. The 197Au Mössbauer parameters were similar to those same species as frozen solutions or adsorbed onto activated carbon. Solvated samples from EuO dissolved in HCl or H2SO4 and frozen gave characteristic Eu(III) spectra. All the spectra were consistent with bonding to the TBP being through hydronium ions or water molecules.
