FIG. 3.

A time course study for the disappearance of RDX (200 mg/liter) and the appearance and disappearance of methylenedinitramine [(O₂NNH)₂CH₂], formaldehyde (HCHO), nitrous oxide (N₂O), and carbon dioxide (¹⁴CO₂) during treatment with municipal anaerobic sludge. The mass area is used for the quantification of methylenedinitramine [(O₂NNH)₂CH₂] because no reference is available. Bis(hydroxymethyl)nitramine [(HOCH₂)₂NNO₂] was not included in the study because its decomposition rate is high and only traces can be detected.
