Degradation of Reactive Brilliant Blue KN-R by Zero-Valent Iron/Activated Carbon Combined with Ultrasound

Abstract:

The treatment of Reactive Brilliant Blue KN-R in wastewater was conducted by using the zero-valent iron/activated carbon (Fe⁰/AC) combined with ultrasound (US). Although ultrasound alone had a little effect on the KN-R degradation and Fe⁰/AC had some disadvantages when it acted on the KN-R, the efficiency of the degradation was dramatically enhanced which used the combination of Fe⁰/AC /U.S. that also could eliminate the shortcomings. The decolorization percentage was nearly up to 100% and the COD removal rate has approached to 87.38%.
