A method for determination of thallium in sulphide geological samples by x-ray Γ‘uorescence spectrometry is presented. The samples were prepared in form of glass discs by fusion with lithium tetraborate and with potassium nitrate as an oxidizing agent. The limit of determination was 0.016% (w/w) Tl,

Microgram quantities of arsenic are determined in geological materials or water samples by copreclpitating the analyte with elemental selenium and using x-ray fluorescence directly on the precipitate. The coprecipitation step removes elemental interferences and converts the sample to a thin film. Th
