The sorption of uranyl ions onto amorphous silica has been studied in the presence of atmospheric CO 2 by laser-induced timeresolved fluorescence spectroscopy at trace concentrations (1.0 and 0.1 Β΅M). Two fluorescent uranyl surface complexes have been identified in the pH range 4 to 9. Both complexe
