Comment on 'Factors Affecting the Yield of Oxidants from the Reaction of Nanoparticulate Zero-Valent Iron and Oxygen'

摘要

In a recent study (1), Keenan and Sedlak investigated the oxidation of four probe compounds (i.e., methanol, ethanol, 2-propanol, and benzoic acid) by the reaction of nanoparticulate zero-valent iron (Fe~0(si) and oxygen (O_2) over a wide range of pH. Their findings are very interesting and advance our understanding on the reaction mechanism and the nature of the oxidants formed during the corrosion of Fe`0_((S)) by O_2. However, mere are several questions related to their research.
