| Summary: | (Pd/Fe'). However, the rate of reduction by Pd/Fe' was 10 hours by Fe' and in 1.5 hours by the same amount of Pd/Fe' 3 hours by both Fe' and Pd/Feo. The only product observed in accounted for 83-100% and all the contaminants in mixed waste was found to be slower anaerobic and aerobic conditions respectively. Since no and in combination. All three target contaminants were complex. contaminant interactions before implementing a ZVMs degradation of 2,4-DAT alone occurred, these results detection limits within dinitrotoluene (2,4-DNT) by zero valent iron and palladized effectively reduced by both iron (Feo) and palladized iron experiments of the contaminants were carried out individually found to be much faster than that by Feo. The reduction of in individual experiment. An initial concentration of 20 indicate the possibility of other intermediates or indicates that there may be a possibility of competition for iron under anaerobic conditions was investigated. Reduction may ultimately slow the whole zero valent metals (ZVMS) mg/L of TCE was reduced below detection limits in 72 hours by mixed waste by Fe' indicates that the reaction mechanisms are mixed wastes containing both inorganic and organic most significant in the 2,4-DNT reduction. This observation of Fe' in 144 hours in individual experiment. The reaction only 42-54% of the initial mass of 2@4.DNT under orders of 1.84 and 2.04 for total TCE loss alone and in Pd/Fe' whereas only 62% of TCE was reduced by the same amount products formation under aerobic conditions. Overall, reactive sites among the contaminants and precipitation Reduction of trichloroethylene (TCE), chromium (VI), and 2,4 remedial system. resulting from CR(VI) reduction may coat iron surfaces, which than in the individual experiments, but the difference was The 20 mg/L of CR(VI) was reduced below detection limits in the reduction of 2,4-DNT The reduction of 72 mg/L of 2,4-DNT proceeded to below the results demonstrated the potential application of treatment process in remediating mixed waste sites. treatment system, which may help in designing a proper was 2,4-diaminotoluene (2,4-DAT). The 2,4-DAT produced ZVMs in reducing |
