Abstract

Although it is well known that zero-valent iron (Fe⁰) rapidly reduces nitro aromatic compounds (NACs) to aromatic amines, little kinetic or mechanistic detail has been reported on the most environmentally-significant NAC: 2,4,6-trinitroluene (TNT). This study provides quantitative kinetics for TNT reduction by a range of reagent- and construction-grade granular irons determined in well-mixed batch systems. A representative surface-area normalized rate constant (k_SA) for construction-grade Fe⁰ is 0.050 1 m^-2 h^-1, but reagent-grade Fe⁰ can be an order of magnitude more reactive.
