摘要

Abstract—

The paper presents the results of water treatment by means of a pulsed-periodic microwave capillary discharge in argon atmosphere. The dynamics of accumulation in the liquid phase of long-lived active forms of oxygen and nitrogen (H2O2, HNO2, \({\text{NO}}_{2}^{-}\) , and \({\text{NO}}_{3}^{-}\) ) and changes in pH during the treatment were investigated. H2O2 is shown to be the main product in the liquid phase. Changes in pH are associated with the formation of HNO2, \({\text{NO}}_{2}^{-}\) , and \({\text{NO}}_{3}^{-}\) . Energy efficiency estimates for hydrogen peroxide production are made, and the resulting values are compared with the corresponding data for continuous microwave discharge.
