| Popis | The separation of a mixture of trinitrotoluenes (TNTs) and their metabolites by reverse phase liquid chromatography using different columns with octadecyl stationary phase is presented. The retention behaviour of a mixture of TNTs and 15 their metabolites was studied under different chromatographic conditions. The mixture of methanol/water was used as a mobile phase in isocratic and gradient modes. The effect of content of organic modifier and temperature of mobile phase has been investigated. Very good RP-HPLC separation of 14 nitroaromatic compounds was obtained using stepped gradient elution. Different properties of 20 extraction procedures for isolation of trinitrotoluenes and their metabolites from soil were tested. Experimental conditions of Soxhlet warm extraction (extractant type, extraction time) suitable for efficient extraction of individual analytes were studied. |
