Abstract
A new approach to the quantitative determination of sulfate sulfur in soils and sediments by wavelength-dispersive X-ray fluorescence spectrometry in combination with partial least squares (PLS) regression has been investigated. The quantitative analysis of sulfate sulfur was carried out by analyzing the spectra in the S-Kα and S-Kβ regions of sulfur spectral lines. The study shows that the differences in the spectra in both regions can be used for quantitative analysis of sulfate sulfur in the presence of sulfur in other forms. The obtained information can be used for quantitative express analysis of sulfur forms in objects of various nature.
