Optimizing degradation conditions of treatment of TATB explosive wastewater by γ-Fe₂O₃ nanoparticles and UV synergistic degradation

Abstract

In this work, the effect of superparamagnetic γ-Fe2O3 nanoparticles/ ultraviolet light (UV) synergistic degradation on the treatment of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) explosive wastewater was studied. γ-Fe2O3 nanoparticles were prepared by hydrolysis method and its degradation performance of TATB explosive wastewater was systematically studied with UV light assisted. The results showed that γ-Fe2O3 magnetic nanoparticles have low a size distribution ranged from 5 nm to 10 nm and possesses superparamagnetic properties. The optimized degradation condition was investigated and best degradation performance was obtained with the optimized conditions: the initial of pH=3, UV illumination intensity (5 w/cm2), reaction temperature (25 °C), initial TOC concentration (4.025 mg/L) as well as reaction time (60 min). This work can offer a new idea to degrade the explosive wastewater.

The Effect of Particle Size of Copper Oxide (CuO) on the Heat‐Induced Catalysis Decomposition of Molecular Perovskite‐Based Energetic Material DAP‐4

“…They suggested a good electrochemical properties in super capacitors [11]. Liu et al showed the nano-Fe 2 O 3 particles were obtained via the hydrothermal method and had the good degradation effect of explosive wastewater under the condition of assisted UV light [12]. These studies revealed that nanoscale metal oxides have good potential applications.…”
