An electrode penetrated by cylindrical holes to inhibit the diffusion of heavy metal ions was proposed. Heavy metal ions diffusing into the holes are reduced to metal and are trapped on the inner surface of the holes. The inhibitory effect was examined using a model electrode made of gold with a cylindrical hole and a solution containing zinc cations. The diffusion of zinc cations was effectively inhibited. Calculations and an EPMA measurement of the elemental zinc on the inner surface of the hole showed that the zinc concentration along the hole decreased rapidly as the distance from the hole inlet increased.
