Comment on "Oxidation of Antibiotics During Water Treatment with Potassium Permanganate: Reaction Pathways and Deactivation [Hu et al., Environ. Sci. Technol., 2011, 45, 3635-3642]"

Authors: Sierra Rayne

In their work, Hu et al. [Environ. Sci. Technol., 2011, 45, 3635-3642] investigate the oxidation of three antibiotics (ciprofloxacin, lincomycin, and trimethoprim) by potassium permanganate in buffered solutions at pH 7. The authors propose detailed mechanistic pathways for the oxidation of these substrates, but apparently do not consider the acid/base behavior of the compounds under consideration, resulting in erroneous mechanistic interpretations throughout the manuscript.
