摘要

Heterogeneous advanced oxidation processes(AOPs)with catalysts can remove recalcitrant organic pollutants in water by generating reactive oxygen species(ROS)through the activation of peroxy precursors(e.g.,hydrogen peroxide,ozone,and peroxymonosulfate(PMS)).These AOPs involve not only adsorption and degradation of pollutants,but also oxidant activation over the catalyst surface.Oxidant concentration is widely recognized to affect the removal efficiency of organic pollutants,but its effect on the specific activity of catalysts has rarely been considered.Here,we use PMS-based AOPs as an example to illustrate how to more accurately evaluate the intrinsic activity of catalysts and optimize PMS activation and process performance.
