UV-VIS and TRLFS speciation study of UO2(2+) - ChO4(2-) system in aqueous solutions (Ch = S, Se)
Original language description
This experimental study seeks for stability constants, absorption and fluorescence spectra (including fluorescence lifetimes) for the individual species of the general formula [UO2(ChO4)n] (n = 0, 1, 2, 3), specific ion interaction theory parameters eps(i,j) between uran-containing species and the most dominantly present ions (Na+, ClO4-, ChO4^(2-), HChO4-) and their temperature dependence (for which the DH° for all present complex species is derived). Our study was done by preparing of several series of solutions (solutions differing by total sulfate/selenate concentration within the series and by total uranium concentration, pH and ionic strength between different series), measurement of the spectra (UV-VIS abs., TRLFS) and subsequent multilinear analysis (based on Singular Value Decomposition, Parallel Factor Analysis, ...). The obtained results are compared with the previously measured data (our TRLFS spectra for uranyl-selenate complex species were, however, in the time of the abs
