Recently, the study about reactions at plasma/liquid interfaces becomes important in plasma technology, because of the various applications of plasmas in and in contact with liquid. Electron spin resonance (ESR) with spin-trapping agents is useful for detecting short-lived free radicals reacting in liquid phase. However, the accurate quantification of radicals requires kinetics of spin-trapping agents under plasma treatment rather than in thermal equilibrium. This study investigated such kinetics by developing in situ ESR coupled to a reactor of plasmas in liquid.
