Abstract
New laser-induced fluorescence method (LFM) are proposed for determination of uranium (VI) in concentration range of 10-7 - 10-11 g/ml and polycyclic aromatic hydrocarbons (PAH) in concentration range 10-7 - 5(DOT)10-10 g/ml in the environment. A repetive pulsed laser, spectral and time discrimination and averaging technique are used. LFM does not need a preconcentration step or separation of VI and PAH from interfering elements. By using LFM new luminescent analyzers were made. The use of the analyzers made possible to perform the VI and PAH determination both in static and dynamic conditions. The time needed for analysis is only 1 - 3 minutes.
