Application of TLC for Analysis of Trinitrotoluene Residues in Environmental Samples

Błądek J., Nowaczewski J., Maranda A.

Central European Journal of Energetic Materials

Vol. 2, nr 4

63-76

The results of researches on possibility of thin-layer chromatography (TLC) application in analysis of after explosion residues of trinitrotoluene in environmental samples are presented. A testing stand for model charges detonation was designed and made. Methods of extraction were specified and recoveries were estimated (they were about 80%). Chromatographic system suitable for analyte separation from other explosives and matrix components was proposed. A linear response curve of changes of densitometric measured A values versus analyte mass c in chromatographic band was received (A = 35 051c - 838). A limit of detection (70 ng) and maximal range of linear measurements (2800 ng) was defined. TLC was used as an analytical method and - in case of more complicated measurements – as a technique of sample preparing for GC/MS measurements?.
