The chemical titration method and ion chromatography method were employed to analyze the ionic form and concentration in the NaClO2solution
NaClO solution and their compound solution during the simultaneous desulfurization and denitrification process qualitatively and quantitatively.The interaction between the NaClO2and NaClO and the mechanism of simultaneous desulfurization and denitrification were discussed.The results showed that
the ClO2and Cl2that produced by reaction between the NaClO2and NaClO was the main oxidant
which can greatly enhance the denitrification efficiency.With the action of the ClOand Cl2
the NO and SO2was oxidized into NO3-and SO42-
and both the denitration and desulfurization efficiency reached above 90%.
