Özet

The concentration of seven different elements in fifteen lichen species from different regions in Artvin-Murgul (Turkey) and their ash was determined using radioisotope excited energy dispersive X-ray fluorescence method of multiple standard addition. An annular 50 mCi Am-241 radioactive source and an annular 50 mCi Fe-55 radioactive source were used for excitation of characteristic K X-rays. An Si(Li)detector, which has a 147 eV full width at half maximum for 5.9 keV photons, was used for intensity measurements. A qualitative analysis of spectral peaks showed that the samples contained potassium, calcium, titanium, iron, copper, strontium and barium.
