RDX degradation by chemical oxidation using calcium peroxide in bench scale sludge systems.

The ability of calcium peroxide (CaO) to degrade hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) in contaminated soil slurries using CaO-based modified Fenton oxidation was investigated. Results showed that increasing the CaO dose increased degradation rates of RDX and pH. RDX concentrations decreased to below detection after 18 h with 2 M and 2.
