Highly Efficient Removal of Organic Pollutants with HCO₃^--Enhanced Ru(III)/NaClO Process.

ABSTRACT: The design of efficient advanced oxidation processes (AOPs) in the presence of bicarbonate has long attracted considerable attention in the field of environmental catalysis. In this study, sodium bicarbonate (NaHCO₃) as one of the most abundant substances in actual water, was introduced to a NaClO/Ru(III) system to enhance the removal of acid orange 7(AO7). NaHCO₃ could significantly improve the removal efficiency of the Ru(III)/NaClO process in HCO₃^- at a pH range of 6.9-10.0. Ru(V)=O was identified as a dominant reactive species involved in the degradation of pollutants in the NaHCO₃/NaClO/Ru(III) system. HCO₃^- interacts with Ru(III) to generate Ru(III)-HCO₃^-, which enhances the activation
