Advanced Redox Technologies (ARTs) are defined as technologies which generate reactive oxidizing or reducing agents (usually radical speices) that are capable of degrading the recalcitrant organic contaminants in water. Our lab focuses on developing more cost-efficient and energy-efficient ARTs to meet future needs for improving water quality. Moreover, we make an effort to modify current advanced oxidation processes (AOPs) to treat emerging recalcitrant contaminants.
