Degradation of 2,4,6-trinitrotoluene (TNT) by potassium ferrate in the presence and absence of sand. The 5 mg of ferrate used removed about 10 mg of TNT. The Y-axis shows mg of TNT added to each microcosm. The Y-axis shows the amount (mg) of added TNT degraded or the percentage remaining after the reaction.
