ABSTRACT
This paper is particularly related to elemental mercury ([Hg.sup.0]) oxidation and divalent mercury ([Hg.sup.2+]) reduction under simulated flue gas conditions in the presence of nitric oxide (NO) and sulfur dioxide (S[O.sub.2]). As a powerful oxidant and chlorinating reagent, [Cl.sub.2] has the potential for Hg oxidation. However, the detailed mechanism for the interactions, especially among chlorine (Cl)-containing species, S[O.sub.2], NO, as well as [H.sub.2]O, remains ambiguous. Research described in this paper therefore focused on the impacts of S[O.sub.2] and NO on [Hg.sup.0] oxidation and [Hg.sup.2+] reduction with the intent of unraveling ...
