The results of the fitting procedure (table i) reveal chat the divalent iron phase is Szomolnokite (FeS04 H20). The trivalent iron phase is probably a hydroxylated basic iron sulfate like Butlerite (FeSC>40H 2H20) [8]. The data also reveal that the catalysts after operation contain well crystallized Szomolnokite, as follows from the observed small line width of its spectral contribution. The presence of die sextuplet in the spectrum of the used catalyst B shows that still some iron(III) oxide is present as also found by XRD. [Pg.478]
