| Abstract: | The preconcentration and voltammetric behavior of aromatic nitro compounds at paste electrodes made of synthetic carbon materials
were studied. The relationship between the energies of adsorption of molecules on active carbons and the peak current constants
was determined. Conditions for the isomer-selective determination ofo- andp-isomers of nitrophenol, nitroaniline, and nitrobenzoic acid in aqueous solutions were optimized. |
