| Abstract | ||
| THE REDUCTION of 2,4,6-trinitrotoluene (TNT) in aqueous solution using nanoscale zero-valent iron was investigated. The results showed that the first order reaction law fits the reduction of TNT. The measured apparent rate constant (Kobs) of TNT on nanoscale zero-valent iron (0.0374 h−1) was 4-fold than on conventional iron powders (0.0091 h−1) at 303 K. The apparent rate constant of TNT reduction on nanoscale zero-valent iron also can be improved by an increase in concentration of nanoscale zero-valent iron and a decrease of pH. | ||
