X-ray fluorescent signals of F Kα, Na Kα, Cl Kα, K Kα, and Ta Lα were measured by WD-XRF for various fluorine-containing systems: K2TaF7, Na3AlF6, K2ZrF6, NaF, and LiF (with NaCl and wax as additional additives). The data were recorded for 41 samples (in the form of pellets prepared in the laboratory) by more than 200 scans. The analysis of the measured fluorine X-ray fluorescence intensities demonstrated that the balance between absorption and enhancement effects depends strongly on the presence and concentration of other elements in the system. The experimental intensities of X-ray fluorescent radiation of fluorine for different systems with comparable fluorine content could differ by as much as 500%.
