Degradation of azo dyes using low iron concentration of Fenton and Fenton-like system.

This study investigated Fenton and Fenton-like reactions at low iron concentration (<or==10 mg l-1) to oxidize three commercial azo dyes, namely Red MX-5B, Reactive Black 5 and Orange G. In some local cases in Taiwan, wastewater color was found to be the only problem in meeting local effluent standards. This investigation reveals that both of these methods… CONTINUE READING
