Voltammetry Study of the 2,4,6-Trinitrotoluene Conversion into the Amine Compounds Using Zero-Valent Iron

Abstract

The paper describes the use of voltammetry in monitoring the reductive process of 2,4,6-trinitrotoluene (TNT) to amine compounds by zero-valent iron. This method to simultaneously determine the reduction of TNT and the increase of Fe²⁺ concentrations in the samples. The method may be applied to establish the efficiency of the conversion process of TNT, the role of zerovalent iron and its efficiency in the reductive process. The factors such as pH, TNT concentration, reaction times and Fe⁽⁰⁾ mass influencing on the conversion process into amine compounds have been studied.
