The odorous gaseous emissions from industrial and wastewater treatment plant processes pose risk for natural ecosystem and human health. This chapter presents an assessment of the potential of ferrate(VI) (FeVIO42-, Fe(VI)) to remove gaseous odor. Organosulfur compounds are usually predominate constituents of the odor and the kinetics, stoichiometry, and products of their oxidation by Fe(VI) is summarized. The second-order rate constants, k, of the oxidation reactions under alkaline conditions were in the range of ∼ 101 - 105 M-1s-1. At a 10 mg L-1 K2FeO4 dose, half-lives of the oxidation reaction would be in seconds or less at pH 9.0. The stoichiometry of the reactions of Fe(VI) with sulfur compounds generally varied from 1:2 to 2:3 and Fe(II) and Fe(III) were the reduced products of Fe(VI). Oxygen-containing products of the sulfur compounds were formed. Examples of case studies showed the efficient removal of odorous gases by Fe(VI).
