The effect of temperature, oxidant concentration and time were studied and the optimal combination of reaction parameters was established using response surface methodology in a Box-Behnken design. Of all the parameters examined, temperature showed the most positive effect on the degradation of the nitroaromatic compounds. Optimal reaction conditions were found to be a temperature of 240 degrees C, 210 degrees C and 236 degrees C, time of 180, 178 and 172 min, oxidant concentration of 100, 99.64 and 99.61 mM for 2,4-DNT, 4-NT and 2-A-4-NT, respectively. Since high-temperature was applied, the possibility of formation of subcriticaldegradation products existed; therefore, total amounts of degraded nitroaromatic compounds and formed intermediate products were determined by gas chromatographic-mass spectrometric analysis.eninfo:eu-repo/semantics/openAccessSubcritical waterDegradationNitroaromatic CompoundsResponse Surface MethodologyBox-BehnkenArticle7723724610.5004/dwt.2017.20778Q3WOS:000407719900032N/A
