Abstract
The radiolytic degradation of 2,4,6-trinitrotoluene and hexahydro-1,3,5-trinitro-1,3,5-triazine in individual aqueous solutions and in real wastewater was studied using the jet mode under an accelerated electron beam. The degree of mineralization of organic compounds and their biodegradability increased due to successive denitration, oxidation, and decarboxylation processes in solutions. The yields of radiolytic degradation of 2,4,6-trinitrotoluene and hexahydro-1,3,5-trinitro-1,3,5-triazine were about 0.027 and 0.064 μmol/J and the corresponding half-life doses were as high as 10 and 1.8 kGy, respectively. The high efficiency of the removal of 2,4,6-trinitrotoluene from real wastewater with the sequential use of coagulation, irradiation, and biological treatment was demonstrated.
