Abstract

Nitroderivatives of toluene such as trinitrotoluenes and products of their biotranformations, aminodinitrotoluenes (ADNT) and diaminonitrotoluenes (DANT) are widely distributed in the environment. These compounds have been found as contaminants in soils at munitions manufacturing facilities, storage depots, and sites of the explosives use. They have mutagenic, carcinogenic and toxic effects [1]. Comparison of retention behaviour of selected nitroderivatives of toluene and aminonitroderivatives of toluene in liquid chromatography (HPLC), capillary electrochromatography (CEC) and micellar electrokinetic chromatography (MECC) separation systems is presented. Effect of pH, concentration of background electrolyte, sodium dodecylsulphate and organic modifier concentration both in electrolyte and mobile phase was investigated. Different gradient elution in reversed phase liquid chromatography system was studied. The applicability of used separation method for determination of toluene nitroderivatives in environmental samples is discussed.
