Abstract

The hydrolysis of Tl(I) has been studied at 25°C using 205Tl-NMR spectroscopy and UV-Vis spectrophotometry in aqueous solutions with ionic strengths maintained by NaClO4 at 2, 4, 6, and 8M. The formation constant and the spectral characteristics for the hydroxo complex, TlOH° have been determined. At high hydroxide ion concentrations there is clear evidence from the UV-Vis data for the formation of a Tl(OH)2- species. The spectrum and an estimated formation constant for this second hydroxo complex are also reported.
