The Determination of Sulfur Species (SulfideSulfate) in
In cement there are two sulfur species present Sulfide (S2-) and sulfate (SO42- calculated as SO3 in cement). Sulfide has 8 electrons in total in the M-shell while sulfate has no electron left in the important outer shell. This difference leads to changes in the spectrum which can be used for the specification of the sulfur compounds The
