NOVELTY - Degrading nitrogen-containing organic pollutant by catalyzing and strengthening supercritical water by ruthenium (Ru)/reduced graphene oxide (rGO) catalysis involves adding nitrogen-containing organic pollutants, hydrogen peroxide and deionized water into reactor, and adding Ru/rGO catalyst to reactor, closing reactor; heating reactor to 400-480 degrees C for supercritical water catalytic oxidation reaction, where reaction time is 20-60 minutes, and finally degradation and denitrification process of nitrogen-containing organic pollutants is completed, where Ru/rGO catalyst includes reduced graphene oxide rGO and active component Ru supported on rGO, and loading amount of active component Ru is 5-35%. USE - Method for degrading nitrogen-containing organic pollutant by catalysing and strengthening supercritical water by Ru/rGO catalysis. ADVANTAGE - The method enables to degrade nitrogen-containing organic pollutant for carbon (C), nitrogen (N) and other elements, which have high removal rate.
