Pencil and Gold Electrode Materials for the Electrochemical Study and Analysis of Dinitrotoluene.

The aim of our work was to investigate practical and robust methods for the electrochemical analysis of DNT. Using gold WEs, we differentiated between the nitro substituents in 2,4- and 2,6-DNT in organic electrolyte systems. Switching to an aqueous electrolyte (2 M HSO), a limit of detection (LOD) of 0.
