Mater. 145 (2007) 305] %R 10.1016/j.jhazmat.2007.07.004 %R 10.23689/fidgeo-2269 %J Journal of Hazardous Materials %V 148 %N 3 %X 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 (Fe0) in a recent article by M. 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. %U http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/6582 %~ FID GEO-LEO e-docs
