Acid Red 17, Acid Yellow 11, Direct Yellow 12, Direct Blue 86 ve Mordant Violet 40 Boyalarının Karışımını İçeren Suyun Arıtılması İçin Gelişmiş Oksidasyon İşlemi

Abstract

The removal of dyes from wastewater is one of the biggest problems in the textile industry for
 both environment and manufacturers. This study examined the possibility of applying ozone 
 (O3) and O3 in combination with ultraviolet (UV) to treat a mixture of synthetic wastewater 
 containing five different dyes (Acid Red 17, Acid Yellow 11, Direct Yellow 12, Direct Blue 86 
 and Mordant Violet 40) for the decolorization efficiency of dyes with different chromophore 
 and anchor groups. The contact time was studied in a batch reactor under the flow of O3 or 
 O3 combined with UV to achieve optimal operating conditions. The results showed that the 
 application of O3 was more effective than UV-assisted ozonation. The advanced oxidation of 
 each dye in this mixture was compared with the removal of the same dye in the solution 
 separately. The results proved that there is only a slight difference in the time required to 
 remove the dye from the mixture and the single dye in the water solution.
