Abstract
An anode for generating available chlorine from seawater by electrolysis which comprises a substrate made of titanium or an alloy thereof, and a coating on said substrate which is made up of an active anode material layer containing 15-85 wt % of platinum, 5-35 wt % of iridium dioxide, and 10-15 wt % of ruthenium dioxide. The anode has greatly improved anode performance such as current efficiency, cell voltage, and durability. Therefor, its use for a long period of time becomes possible in any condition of seawater.
