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 <i>K</i>α1 line interferes spectrally with the barium first-order (I) <i>L</i>α1 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.
