2,4 Dinitroanisole (DNAN) is an organic insensitive munition that is a likely candidate to replace trinitrotoluene (TNT) for a variety of purposes. Advanced Oxidation Processes (AOPs) are a promising method that have the potential to reduce a variety of persistent chemicals, however, the performance of these systems may be degraded by co-contaminants in the influent. In this contribution, DNAN, with casamino acids as a co-contaminant, was oxidized with Ultraviolet (UV) Light Emitting Diodes (LEDs) with hydrogen peroxide (H2O2) in an AOP in a laboratory. The UV/ H2O2 AOP was capable of degrading DNAN with casamino acids present, from a relative concentration (C/C0) of 1.0 0.63 over a molar peroxide ratio (H2O2: DNAN) range of 50:1 to 1000:1. An increase in the degradation rate of DNAN was observed with increased concentrations of H2O2. The pseudo first order rate constant for DNAN removal was typically greatest at 250:1 and 500:1. The presence of casamino acids had minimal effects on the effectiveness of the AOP, possibly due to light screening.
