| Abstract: | The cathodic reduction of oxygen at graphite electrode was investigated. The electrogenerated hydroxyl radicals, an strong oxidizing agent, which are generated by the reaction of hydrogen peroxide (H 2O 2) produced in the cathodic reduction of oxygen at graphite electrode with ferrous ions formed as a result of the anodic dissolution of iron, was used to treat wastewater containing organic substances, such as active black (an azo dye) and yeast In the case of treating imitated wastewater containing only active black, the COD Cr removal was found to be 20 points higher in percentage in the presence of continuously bubbling oxygen than that in the absence of oxygen. |
