Kinetics of Parachloroaniline Decomposition in a Water Cathode Under the Action of a DC Discharge at Atmospheric Pressure in Oxygen: Modeling and Experiment

ABSTRACT A 0‐D model is proposed that describes the processes in a system including a DC discharge at atmospheric pressure in oxygen and an aqueous solution of parachloroaniline (PCA). The model consisted of coupled subsystems: plasma and solution. The plasma characteristics were found by jointly solving the Boltzmann equation for electrons, the equations of vibrational kinetics, and the equations of chemical kinetics. The kinetics of reactions in the solution included 86 reactions and 24 components. The kinetics of PCA consumption were measured. The rate constants of this process were determined, and a mechanism for PCA decomposition processes was proposed. The results of the modeling are consistent with the experiment.
