A process for detecting nitrotoluenes, particularly trinitrotoluene, dinitrotoluene and derivatives of nitrotoluenes in soils, liquids and gases is proposed and a voltage is applied to an electrode which is in contact with an electrolytic solution having the substance to be tested, the voltage being reduced for producing a reduction reaction and increased for producing an oxidation reaction and the current intensity of at least a residual current and an anodic current maximum occurring is determined, particularly as a function of the voltage applied.
