Formation of active species in spark corona discharge at a liquid electrode

摘要

The formation of chemically active species upon a spark corona discharge on a liquid electrode at the liquid surface. Test liquids were 0.1 M and 0.005 M oxalic acid, 0.1 M KI and 3% KC1 solutions, and tap water. It was found that the reaction yield due to the active species (which might include hydroxyl radicals) was substantially higher in the case of liquid electrode, depending on the electrode-liquid composition.
