Reaction of various kinds of water–soluble dyes with ozone was examined. It was found that the reaction of dyes with ozone improved their biodegradability, and the values of biochemical oxygen demand (BOD} and total organic carbon (TOC) of the ozonation products correlated with those of the theoretical TOC of the original dyes. In addition, the azo dyes had a tendency to be easily decomposed with ozone, and the decomposition of dyes was markedly accelerated when ozonation was accompanied by ultra–violet irradiation.
