Popis:	The kinetic phosphorimetric determination of uranyl ion in aqueous solutions at room temperature yielded a detection limit for UO 2 2+ of 1 ng/L. The response to uranium is linear from the detection limit up to 5 mg/L. The method is fast and accurate, with no separative pretreatment needed for most of the real samples investigated. In the analysis of biological samples, wet-ashing with HNO 3 /H 2 O 2 is required for measurements near the detection limit
