Coactivation of Hydrogen Peroxide Using Pyrogenic Carbon and Magnetite for Sustainable Oxidation of Organic Pollutants.

ABSTRACT: Pyrogenic carbon and magnetite (Fe₃O₄) were mixed together for the activation of hydrogen peroxide (H₂O₂), aiming to enhance the oxidation of refractory pollutants in a sustainable way. The experimental results indicated that the straw-derived carbon obtained by pyrolysis at 500-800 °C was efficient on coactivation of H₂O₂, and the most efficient one was that prepared at 700 °C (C700) featured with abundant defects. Specifically, the reaction rate constant (k_obs) for removal of an antibiotic ciprofloxacin in the coactivation system (C700/Fe₃O₄/H₂O₂) is 12.5 times that in the magnetite-catalyzed system (Fe₃O₄/H₂O₂).
