Mossbauer investigation of the reaction of ferrate(VI) with sulfamethoxazole and aniline in alkaline medium Academic Article

abstract

• Mechanisms on the oxidation of sulfamethoxazole (SMX) and aniline by ferrate(VI) (FeVIO42-, Fe(VI)) in alkaline medium suggested the formation of Fe(VI)-SMX or Fe(VI)-aniline intermediates, respectively. Fe(V) and Fe(IV) as other intermediate iron species have also been proposed in the mechanism. In this paper, rapid freeze Mssbauer spectroscopy was applied in rapidly frozen samples to explore intermediate iron species in the reactions of SMX and aniline with Fe(VI). In both reactions, Fe(VI)-SMX and Fe(VI)-aniline intermediates were not seen in second-minute time scale. Fe(V) and Fe(IV) were also not observed. Fe(III) was the only final species of the reactions. 2013 Springer Science+Business Media Dordrecht.
