| Popis: | Gas-phase pulsed corona discharge (PCD) shows promising energy efficiency in oxidation of aqueous pollutants. Further progress requires knowledge in efficiency dependent on the contact surface of treated water sprinkled to the discharge zone. Experimental studies focused on the dependency used phenol and oxalate solutions at various pH for variable oxidation kinetics. For slow reactions within the experimental limits, oxidation rate was growing substantially with the spray density. Rapid oxidation showed an optimum spray density determined by discharge power at sufficiently developed interface. The oxidation kinetics fits to description of a pseudo-second order process predicting optimum choice of sprinkling rate. |
