Fenton reaction hydroxyl radical
WebMay 21, 2015 · Hydroxyl radicals were captured by benzoic acid and form hydroxybenzoic acid with fluorescence properties [43]. Thus, the higher spectral peak value in Fig. 10 (d) implies that more hydroxyl... WebDec 30, 2013 · A lingering issue regarding Fenton’s reaction is how the relative yields of ferryls vs. ·OH radicals depend on the medium. For example, by assuming unitary ·OH radical yields, some estimates suggest that Fenton’s reaction might account for ∼30% of the ·OH radical production in fog droplets (20).
