title: Application of Continuous-Flow HPLC-Proton-Nuclear Magnetic Resonance Spectroscopy and HPLC-Thermospray-Mass Spectroscopy for the Structural Elucidation of Phototransformation Products of 2,4,6-Trinitrotoluene.
abstract: An aqueous solution of 2,4,6-trinitrotoluene (TNT) was irradiated by natural sunlight for a period of 1 month to generate phototransformation products of this compound. After solid-phase extraction on a poly(styrene-divinylbenzene) copolymer at pH 1, the structures of several acidic nitroaromatic compounds were identified by means of continuous-flow HPLC/(1)H NMR and HPLC/TSP-MS measurements of this extract. By interpretation of both NMR and MS spectra, it was even possible to characterize noncommercially available phototransformation products of TNT. The results obtained by continuous-flow HPLC/(1)H NMR were compared with those obtained by the investigation of a groundwater sample of a former ammunition site near Elsnig, Germany. The results show that several identified phototransformation products of TNT are also present in this groundwater sample.
