High-Ionic-Strength Wastewater Treatment via Catalytic Wet Oxidation over a MnCeO _x Catalyst.

ABSTRACT: Catalytic wastewater treatment has rarely been applied to treat high-ionic-strength wastewater (HISWW) as it contains large amounts of catalyst poisons (e.g., Cl^-). This work investigates the catalytic wet oxidation (CWO) of phenol over a MnCeO _x catalyst in the presence of high NaCl concentrations where the combination of MnCeO _x and NaCl promoted the CWO of phenol. Specifically, in the presence of NaCl at a concentration of 200 g L^-1 and MnCeO _x at a concentration of 1.0 g L^-1, phenol (initially 1.0 g L^-1) and total organic carbon (TOC) conversions were ∼98 and 85%, respectively, after a 24 h reaction. Conversely, under the same reaction conditions without NaCl, the catalytic system only ach
