Comment on "Reductive dechlorination of gamma-hexachloro-cyclohexane using Fe-Pd bimetallic nanoparticles" by Nagpal et al. [J. Hazard. Mater. 175 (2010) 680-687].
The author used a recent article on lindane reductive dechlorination by Fe/Pd bimetallics to complain that dozen of published works in several journals are not conform to the state-of-the-art knowledge on the mechanism of aqueous contaminant removal by metallic iron (e.g. in Fe(0)/H(2)O systems). It is shown that the contribution of adsorbed Fe(II) to the process of contaminant reduction has been neglected while discussing the whole process of contaminant reduction in the presence of bimetallics.
