Application

  • Nonthermal Plasma in Wastewater Treatment: This research utilized nonthermal plasma-based advanced oxidation processes (AOPs) for degrading micropollutants, including isothiazolinones, in wastewater. The study underscores the effectiveness of 2-Octyl-4-isothiazolin-3-one in microbial growth control, providing insights into its applications in wastewater management and microbial contamination control (Chen et al., 2023).
  • Surface Interactions of Semi-Volatile Isothiazolinones: The study quantified the equilibria of semi-volatile isothiazolinones, such as 2-Octyl-4-isothiazolin-3-one, between air and glass surfaces, using techniques like gas chromatography and Raman spectroscopy. This research is vital for understanding the stability and persistence of 2-Octyl-4-isothiazolin-3-one in various environments, particularly its use in biotech applications (Sohn et al., 2023).
