Popis:	Synthetic organic dyes were decomposed rapidly by ozone. The dyes all adhered well to first order kinetics with the exception of the Direct Yellow 12 which showed an initial zero order phase at pH 5. This has been tentatively ascribed to attack by unhydrolyzed ozone on the ethylenlc double bond. From one to four millimoles per liter of ozone was sufficient to attain a 5O% reduction in the concentration of all dyes during the first order ozonations.
