Dynamic analysis of absorbance behavior and peak shift of RONS in plasma-activated water by UV absorption spectroscopy: dependency on gas impurity, pulse polarity, and solution pH

Zhijie Liu et al.

Summary: This study utilized UV absorption spectroscopy to investigate the generation and permeation of reactive oxygen and nitrogen species (RONS) in plasma-activated water (PAW). The results showed that parameters like gas impurity, pulse polarity, and solution pH value significantly influenced the absorbance behavior and peak shift of absorption spectra of RONS. Additionally, the study found that introducing air and N-2 increased RONS absorbance, while the addition of O-2 decreased it. Moreover, the permeation distribution of H2O2 and NO2- was affected by different parameter conditions, indicating the complex relationship between RONS in PAW.
