Description
Summary:Trinitrotoluene (TNT), a nitroaromatic explosive, is encountered groundwater contaminant that can pose a human health risk, even at very low aqueous concentrations. In this study, a series of catalytic degradation of dissolved TNT have been investigated using iron nanocatalysts (zero valent and its oxide) and Fe2O3 bentonite nanocomposite. The prepared nano catalysts were characterized via XRD, BET and TEM. The degradation of TNT by Fe-PILC, is almost complete after 30 min, whereas 65, 100 min on using the Fe-zero valent and Fe-oxide, respectively. These results indicate that the reaction rate is a strong function of the number of iron surface active sites, and therefore the Fe-catalysts an important reaction variable.
