Abstract
Time-resolved laser-induced fluorescence has been shown to be effective for on-line measurement of uranyl chelates in supercritical carbon dioxide. Qu enching and other factors affecting the method's accuracy were identified a nd quantified to allow for accurate measurements under variable supercritic al fluid conditions. The method was applied to the kinetic analysis of uran ium extraction from acidic solutions with tributyl phosphate modified super critical carbon dioxide.
