Notice of RetractionMicrowave Intensified and Regenerated Iron Chippings/Coconut-Shell Activated Carbon System to Degrade Reactive Brilliant Red K-2BP in Water

Abstract

In this paper, we have attempt to use microwave (MW) to intensify and regenerate iron chippings (IC)/coconut-shell activated carbon (CSAC) for degradation of Reactive Brilliant Red K-2BP (K-2BP). The result showed that MW could intensify and regenerate IC/CSAC system and higher color removal percentage (CR%) and chemical oxygen demand reduction (CODR%) were achieved after MW irradiation. Meanwhile, the relationships between degradation efficiencies and those factors such as MW irradiation time, repeat treatment times and proportion between CSAC and IC, were discussed. We found the optimal MW irradiation time and ratio of CSAC/IC (v/v) were 2 min and 1:1, respectively.
