抄録

The dissolution rate and the dissolution factor of copper immersed in a dilute anodically electrolyzed water of sodium sulfate aqueous solution (Na₂SO₄-acidic electrolyzed water) and in a sulfuric acid aqueous solution of the same pH were studied. As a result, it was found that the dissolution rate of copper in the former was about 3 times higher than that in the latter. The phenomenon of the dissolution of copper being enhanced in the Na₂SO₄-acidic electrolyzed water is considered to be attributable to the existence of high concentrations of dissolved oxygen and hydroxyl radical precursor that it is most likely synergistically produced by electrolysis. Furthermore, it was suggested that Na₂SO₄-acidic electrolyzed water is capable of functioning as an etchant and roughening agent for copper instead of a sulfuric acid/hydrogen peroxide mixture.
