Description

Infrared spectra of uranyl(VI) species adsorbed from aqeuous [UO2(CO3)3]4- solutions on to a polymer having amidoxime groups were examined in order to obtain information on the adsorption mechanism. The subtraction spectra in a region of 500-1 500 cm-1 exhibit only a distinct band at 886 cm-1 ascribed to the v3 mode of the O=U=O moiety and no band assigned to carbonato ligands, suggesting the existence of a carbonato-free uranyl(VI) complex; this is consistent with the adsorption equilibrium reported previously.
