title: [Determination of the valence of iron by the conventional XRF spectrometer].
abstract: FeKbeta emission spectra and parameters of mixtures are studied by conventional XRF spectrometer and PEAKFIT programs. The true spectra profile and it's parameters are obtained by profile resolving method. Integral area ratios are also calculated. The relations of these parameters and the valences of the iron are found. Fe3O4 sample and the iron ore which has different valences are quantified.
