Decolorization and COD Removal of Reactive Yellow 16 by Fenton Oxidation and Comparison of Dye Removal with Photo Fenton and Sono Fenton Process

摘要

Wastewaters from textile industry contain various pollutants including a high content of organic matter, surfactants, additives and dyes. Dyes have obtained notoriety as hazardous substances, because most of them are toxic and considered to be resistant to biodegradation. Recently, advanced oxidation processes (AOP) have received considerable attention because it is possible to degrade organic compounds and color from wastewaters. This study was performed to investigate the removal of COD and color for Reactive yellow 16 using Fenton oxidation. The comparisons of removal efficiencies were made among Fenton, Photo Fenton and Sono Fenton process. Removal of COD and color of 80% & 90%, 90% & 98%, and 82% & 95% can be achieved by Fenton, Photo Fenton and Sono Fenton process. The results showed that H 2 O 2 /Fe 2+ /UV process was more effective in COD and color removal.
