Abstract:
Illumination of tetraphenyl porphyrin sulfonate (TPPS), CuTPPs and FeTTPPS in solution with trinitrotoluene (TNT) at pH7 at room temperature using tungsten lamp illumination results in the degradation of TNT to yield trinitrobenzoic acid and trinitrobenzene. No other degradation products are observed. The rate of TNT degradation follows the series TPPS > FeTPPS > CuTPPS.
