The ability of calcium peroxide (CaO₂) to degrade hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) in contaminated soil slurries using CaO₂-based modified Fenton oxidation was investigated. Results showed that increasing the CaO₂ dose increased degradation rates of RDX and pH. RDX concentrations decreased to below detection after 18 hours with 2 M and 2.5 M CaO₂, after 30 hours with 1.5 M CaO₂, after 54 hours with 1 M CaO₂, but 0.1 M CaO₂ achieved no significant RDX removal. Increasing the soil organic matter content decreased the rate and extent of RDX degradation. RDX degradation products 4-nitro-2,4-diazabutanal (NDAB) and methylenedinitramine (MEDINA) were quantified, and the greater accumulation of NDAB than MEDINA suggests denitration of RDX was the most likely initial degradation step. Isotopic ratios for nitrogen and oxygen associated with RDX oxidation are also consistent with either nitrification of NH₄⁺ from soil or precipitation. Existing technologies merely only extract energetics from soils for treatment ex situ, whereas the approach introduced herein destroys RDX in situ with a one-step application.

使用基于CaO ₂的改良Fenton氧化技术研究了过氧化钙（CaO ₂）降解受污染土壤泥浆中六氢-1,3,5-三硝基-1,3,5-三嗪（RDX）的能力。结果表明，增加CaO ₂剂量会增加RDX和pH的降解率。在使用2 M和2.5 M CaO _2的18小时之后，使用1.5 M CaO _2的30小时之后，使用1 M CaO _2的54小时之后，但是使用0.1 M CaO _{2的情况下}，RDX浓度降至检测不到未实现明显的RDX移除。增加土壤有机质含量降低了RDX降解的速率和程度。对RDX降解产物4-硝基-2,4-二氮杂丁醛（NDAB）和亚甲基化二乙胺（MEDINA）进行了定量，并且NDAB的积累量大于MEDINA，这表明RDX的脱硝是最可能的初始降解步骤。与RDX氧化有关的氮和氧的同位素比也与土壤中NH ₄ ^+的硝化或降水一致。现有技术仅仅只从土壤中用于治疗提取能量学易地，而本文中所介绍的方法破坏RDX原位用一步法应用。
