| Abstract | BIOSIS COPYRIGHT: BIOL ABS. The oxidation of high explosives (HE), TNT, RDX and HMX, contaminated water has been studied under different conditions. Catalytic and advanced oxidation employing ultraviolet and hydrogen peroxide were investigated. Catalytic and non-catalytic wet oxidation of HE were carried over a 4.45 wt% PtiO2 catalyst with a particle diameter of less than 105 mum in a batch reactor at moderate pressure (|35 atm) and temperature (|200?C). Ultraviolet photolysis in combination with hydrogen peroxide oxidat mildly dependent on the amount of catalyst. The presence of catalyst resulted in about 20?C advantage in catalytic oxidation when compared to homogeneous wet oxidation. Also RDX/HMX oxidation was relatively easy without the presence of a catalyst at temperatures as low as 85?C and complete oxidation occurs at above 110?C in less than 30 min. Direct photolysis of RDX/HMX was accomplished in about 20 min whereas TNT was the most stable compound and the presence of hydrogen peroxide w |
