Abstract: | A resonance light scattering (RLS) method for the direct detection of uranium (VI) or uranyl in aqueous solution without separation procedure has been reported in this paper. Sulfo-salophen, a water-soluble tetradentate Schiff base ligand of uranyl, reacted with uranyl to form a complex. The complex reacted further with oxalate to form supramolecular dimer with large molecular volume, resulting in a production of strong RLS signal. The amount of uranium (VI) was detected through measuring the RLS intensity. A linear range was found to be 0.2–30.0 ng/mL under optimal conditions with a detection limit of 0.15 ng/mL. The method has been applied to determine uranium (VI) in environmental water samples with the relative standard deviations of less than 5 % and the recoveries of 98.8–105.8 %. The present technique is suitable for the assay of uranium (VI) in environmental water samples collected from different sources. |
