Study of the speciation in the system UO2(2+)-SO4(2-)-H2O by means of the UV-VIS spectrophotometry
Original language description
This work estimates speciation characteristics of the UO22+ - SO42- - H2O system by means of the analysis of UV-VIS absorption spectra of series of aqueous solutions of uranium(VI) (total molar concentration 0.05 mol.dm-3), sodium sulfate (varying concentration from 0 to 1.3 mol.dm-3), perchloric acid (to adjust pH = 2) and sodium perchlorate (to adjust ionic strength I in each series (between different series I varied from 0.7 mol.Kg-1 to 4.0 mol.Kg-1)). log beta° for several complexes were estimated by SVD-based mathematical analysis of spectra. The existence of isomers of uranyl(VI)-sulfate complexes is discussed.
