ABSTRACT:
A method for the oxidation of organic material present in concentrated sulfuric acid is disclosed. The method comprises the steps of diverting a portion of a concentrated sulfuric acid stream, diluting the diverted stream with water to about 40-70% sulfuric acid concentration, passing the diluted stream through an electrolysis apparatus to oxidize some of the sulfuric acid to form a predetermined quantity of peroxosulfuric acids, and returning the diverted stream back to the main stream to oxidize the organic material and decolorize the main stream of concentrated sulfuric acid.
