| Abstract | The determination of hexahydro-1,3,5-trinitro-1,3,5-triazine (121824) (RDX), 2,4,6-trinitrotoluene (118967) (TNT), and other nitroaromatic compounds in environmental samples using high performance liquid chromatography (HPLC) with photodiode array detection was described. Tested were three mobile phases: isocratic methanol/water (50:50), a methanol/water gradient, and a methanol water gradient containing 2% tetrahydrofuran (THF). Results showed that under the isocratic conditions used, the diaminonitrotoluene isomers were not retained, while the azoxytoluenes did not elute within 70 minutes. Several HPLC runs with different isocratic conditions were necessary to measure all these compounds. Under gradient programmed conditions, a single HPLC run of 21 substances resulted in nearly complete separation in which the two diaminonitrotoluene isomers were eluted first followed by the RDX, the other TNT, mononitrotoluenes and dinitrotoluenes, and azoxy compounds. The reproducibility of the method was tested by making repeated injections of a standard solution of the compounds. The behavior of the compounds on a reversed phased RP-18 column with and without the addition of THF showed that the separation for TNT and nitrated benzene was excellent when THF was added, but that the separation of aminodinitrotoluenes and 2-nitrotoluene was better when the gradient system alone was used. The authors conclude that the complexity of the sample matrix may determine the system of preference. Photodiode array detection further confirms peak identity. |
