- Аннотация: Samples of technogenic raw materials are studied by spectroscopic methods. The chemical composition of a roast slag and a charge of vanadium production is analyzed by the X-ray fluorescence method (XRF). The possibilities of X-ray photoelectron spectroscopy are studied for determination of the oxidation state of elements in technogenic raw materials. It is found that similar to 30% of V occurs in the slag as V(III), whereas, in the charge, the content of V(V) and V(IV) is similar to 80 and 20%, respectively; no V compounds with the lowest oxidation states are found. Iron in the slag and charge samples is present as Fe3O4, and Mn mostly occurs as Mn(III). The oxidation state of V in the slag and charge can be determined by the intensity ratio of the K and L lines of the XRF spectra; however, this method is not recommended because of its low accuracy.
