Abstract

Aim To study the degradation of TNT in water by ozone-ultraviolet advanced oxidation process (O₃ + UV). Methods The concentration changes of various compounds such as TNT, trinitroaromatic compounds, O₃, etc. were investigated by experiments. Results and Conclusion TNT can be degraded more faster by combining O₃ with UV radiation while very slowly by only using O₃. A high pH does not improve the removal efficiency of O₃ + UV process significantly. There still exist some trinitroaromatic compounds in the solution after TNT being processed, and theywill reduce slowly after the mass fraction is less than 25%. The O ₃ + UV process is not suitable for the final-treatment of trinitroaromatic compounds.
