摘要：

emission line profiles of Ca, Zn, and Mg in the inductively coupled plasma discharge were investigated by means of atomic fluorescence spectrometry. The combination of the experimentally obtained excitation and fluorescence curves of growth allowed the self-absorption and self-reversal effects on the emitted profiles to be qualitatively detected. In such measurements the flame is used as a resonance detector. The results show that self-absorption, while present, is not severe and that self-reversal is absent in the observation zones commonly used for analytical measurements. Furthermore, the use of the inductively coupled plasma as excitation source in flame atomic fluorescence spectrometry permitted low limits of detection to be achieved with a simple experimental setup. © 1979, American Chemical Society.
