Abstract
This paper describes a new procedure for the direct determination of uranium in plutonium solutions using time-resolved spectrofluorometry. The analytical method is based upon the use of sulfuric acid as a dilution medium and leads to a detection limit of U/Pu = 0.2 ppm. A formula taking into account both quenching and inner-filter effects is presented. It permits the calculation of the detection limit or uranium in complex solutions and could be used to obtain a theoretical limit of detection for similar applications.
