Abstract

The sensitivity demonstrated for other nitro-aromatic explosives through SERS has been applied to triaminotrinitro-benzene (TATB). Gas phase and solution phase in strong acids and bases, as well as organic solvents SERS spectra have been collected. For each method of TATB sample introduction on electrochemically roughened gold substrates or gold colloids, different bands and sensitivities were observed. These bands likely result from the three possible adsorption sites in the molecule and its reaction with the gold surface. In some cases, the SERS spectra closely overlapped the carbonaceous background and indicate TATB degradation. Although the mechanisms of the reaction of TATB with the surface are not understood, important aspects of optimized TATB SERS detection have been observed. Para-nitroaniline (p-NA) was also studied due to its similarity with TATB and its greater solubility in water.
