Abstract

The invention relates to a method of decomposing organic compounds in water which has a TOC content of more than 2 ppm and a content of carbonic acid and carbonates dissolved therein, by treating the mixture with ozone. The invention further relates to a method of producing chlorine by subjecting sodium chloride to an electrolysis. The inventive method is characterized in that the sodium chloride is used in said electrolysis in the form of an aqueous solution that is obtained by treating water with ozone, said water having a TOC content of more than 2 ppm and a sodium chloride content of 2 to 20 wt.- % and additional carbonic acid and carbonates dissolved therein.
