Consider the choice of coating anodes for electrolysis of sodium hypochlorite nizkokontsentrovannogo 3% solution of sodium salt of food and water of the Black Sea. Defined corrosion resistance of anodes with different laying oxides of ruthenium and iridium and their characteristics: yield chlorine-current voltage on the cell growth dynamics of the concentration of active chlorine in the solution.

Keywords: oxide coatings, iridium, ruthenium, low concentration of sodium hypochlorite, the corrosion resistance of anodes according to the output current of chlorine, the electrolysis of a 3% solution of sodium edible salt and sea water.
