Abstract:Wavelength dispersive X‐ray fluorescence (WD‐XRF) spectrometry is a fast and widely used technique for elemental analysis of geological samples from Na to U. However, it has seldom been applied for quantitative determination of oxidation states of elements in complex matrices. In this study, we present a method to determine the oxidation states of iron in geological samples by WD‐XRF. We used the FeLα1,2 fluorescence line as a tool for iron speciation and Fe(II)/Fetotal ratio determination. We found that the n… Show more
