HPLC with electrochemical detection using a carbon paste electrode based on glassy carbon spherical microparticles with an organic pasting liquid has been used for the determination of trace amounts of carcinogenic 1-naphthylamine, 2-naphthylamine, 1,5-diaminonaphthalene and 1,8-diaminonaphthalene. The lowest limit of detection found was 5.4 × 10-9 mol L-1 for 1,5-diaminonaphthalene. The limits of detection for the above analytes using the electrochemical detection with a carbon paste electrode were in all cases lower than the corresponding limits of detection for the spectrophotometric detection. The newly developed method of determination was verified on model samples of drinking and river water.
