Effect of Process Parameters on HNO _<i>y</i>=2,3 and NO _<i>y</i> ^- Formation in Plasma-Treated Water.

ABSTRACT: Here, we investigate the effects of hydrodynamics and temperature on the formation of nitrous and nitric acids (HNO _y=2,3) and their conjugate bases (NO _y ^-) in plasma-treated water (PTW) in a surface dielectric barrier discharge (sDBD) reactor. The stirring rate and bulk water temperature were systematically varied from 200 to 1000 rpm and 20 to 80 °C, respectively, while the plasma was held constant. Species in both the gas and liquid phases were tracked in real time using synchronized dual optical absorption spectroscopy, allowing correlation of the gas-phase O₃/NO _x=1-3 dynamics with the evolving aqueous species of NO₂ ^-, HNO₂, and NO₃ ^-.
