Photocatalytic Transformations and Degradation of 2,4,6-trinitrotoluene (TNT) in TiO2 Slurries
Daniel C. Schmelling, Kimberly A. Gray · 1994
The photodegradation of TNT in a TiO 2 slurry reactor was studied as both a potential treatment technique for the remediation of water with munitions contamination and to gain further insight into the behavior of a nitroaromatic compound in a photocatalytic system. Photocatalytic and direct photolytic reactions were compared by evaluating rates and extent of TNT transformation and mineralization in the presence and absence of oxygen. Nitrate, nitrite, and ammonium ion concentrations were determined and mass balances on carbon and nitrogen were performed for the catalytic system.
