What is OH in water treatment?
•OH are nonselective and oxidize many organic compounds. Advanced oxidation processes (AOPs) for water treatment normally combine either ozone or UV irradiation with H2O2 to produce •OH. Both processes are energy-intensive, require on-site chemical storage or production, and produce •OH within reactors having only 10 s to 20 min residence times. While •OH concentrations are on the order of 0.01 nM in drinking or wastewaters during ozonation, there are no reports of •OH measurements during nanobubbles applications. Thus, a method to quantify •OH produced during NB treatments is needed to compare NBs to current AOPs used in water treatment, and this is one of my research objects recently. However, after reading lots of publications still have no idea about what approach is most proper to achieve this target.
