Abstract
An activated carbon for use as a polarized electrode is brought into contact with an organic compound which forms an azeotropic mixture with water, so that the activated carbon is impregnated with the organic compound. Then, the activated carbon impregnated with the organic compound is dried with heat to remove the azeotropic mixture of the organic compound and the water. The activated carbon is immersed in the organic compound to impregnate the activated carbon with the organic compound. Preferably, when the organic compound forms an azeotropic mixture with water, the azeotropic mixture contains 28 weight % of water or more. The organic compound preferably comprises at least one compound selected from the group consisting of benzene, chlorobenzene, ethyl acetate, methyl ethyl ketone, 1,4-dioxane, and methyl acetate, and more preferably comprises benzene.
