The effect of substituent groups on the reductive degradation of azo dyes by zerovalent iron - Comments

[摘要] This letter discusses possible improvements in experimental conditions to enable a purposeful discussion on the effect of substituent groups on the reductive degradation of azo dyes by elemental iron (Fe-0) in a recent article by Hou and his co-workers. Also recalled is the pH dependence of the iron corrosion mechanism which is usually overlooked in the iron technology literature. (C) 2007 Elsevier B.V. All rights reserved.
