In a new study published in the journal Frontiers of Environmental Science & Engineering, researchers from University of Toronto identified the most effective and practical quenching agent for use in drinking water treatment plants. The findings emphasize the crucial significance of selecting an appropriate quenching agent, a decision that plays a key role in the context of drinking water treatment.

In this comprehensive study, researchers delved into the kinetics of hydrogen peroxide quenching following the UV/H2O2 advanced oxidation process, focusing on thiosulfate, bisulfite, and chlorine as potential agents. These substances were specifically chosen for their varied effectiveness in degrading residual hydrogen peroxide. The primary objective was to ascertain the most efficient and feasible quenching agent for application in drinking water treatment plants.
