Comments on "Decontamination of solutions containing EDTA using metallic iron" by Gyliene O., et al. [J. Hazard. Mater. (2008)]

J Hazard Mater. 2009 Jun 15;165(1-3):1261-3. doi: 10.1016/j.jhazmat.2008.09.026. Epub 2008 Sep 13.

Abstract

This letter presents an improved discussion of the data provided in a recent article on EDTA removal from aqueous solutions using elemental iron (Fe(0)) by O. Gyliene and his co-workers. It is shown that the authors have furnished a brilliant validation of the concept that dissolved contaminants are primary removed in Fe(0)/H(2)O systems by adsorption onto iron corrosion products and co-precipitation with iron corrosion products. It is reiterated that "contaminant removal" and "contaminant reduction" should not be interchanged randomly.
