摘要：

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(styryene-divinyl-benzene) copolymer at pH 1, the structures of several acidic nitroaromatic compounds were identified by means of continuous-now HPLC/H-1 NMR and HPLC/TSP-MS measurements of this ex tract. 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-now HPLC/H-1 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 TWT are also present in this groundwater sample.
