Abstract
- We studied a possibility of determining fluorine in rocks by the X-ray fluorescence spectrometry using pressed pellets as emitters. The most important factors affecting the results of fluorine determination are considered, namely, the covering effect , systematic and random errors due to measuring the intensity of the fluorine line and sample preparation, the dependence of the FKα line intensity on the matrix composition of the sample and the compound containing this element. The results were evaluated in terms of permissible errors. The use of a single calibration equation for rocks with various fluorine-containing minerals is inapplicable to pressed pellets.
