Among the laser methods used in atomic spectroscopy, atomic fluorescence resonance spectroscopy together with an atomic ionization technique make it possible to work with individual atoms. This paper reports on the determination of Na and Ba in aqueous solutions of their salts with atomic fluorescence analysis performed wih a dye laser and lamp pumping, the pulse of generation having a length of 1-2 usec. The detection limit of elements in atomic fluorescence analysis performed wih dye lasers with lamp pumping can be reduced by increasing the spectral density of the laser radiation through narrowing the line of generation, by employing other dyes to excite lines of greater intensity, by improving the recording system of the fluorescence spectra, and by improving the atomization of the samples to be analyzed.
