Abstract
It is possible to accurately determine barium and strontium in a variety of geologic samples by the XRF method proposed herein after correcting for matrix effects. The first-order (I) titanium Kα1 line interferes spectrally with the barium first-order (I) Lα1 analytical line. Iron significantly absorbs the emitted strontium x-ray quanta. Both of these effects were investigated in detail and a method of correcting for them developed. Detection limit for both elements is about 10 ppm.
