[Determination of metal dusts in aerosols using x-ray fluorescence. Comparison with other analytical methods].
Determination of metals in aerosol collected as thin layer on membran filters has made employing X-ray fluorescence. Standards are prepared in suitable chambers: dust collected on membran filter is weighted. The problems of methodology are discussed. Calibration curves have been prepared for Pb - Fe - Cd - Si; comparisons have been made with other methods employing atomic absorption spectroscopy.
