The voltammetric determination of 2-aminofluorene and 2,7-diaminofluorene based on their oxidation on carbon paste electrode is described. Britton-Robinson buffer and pH ranges 1-3 and 10-12 are recommended for the simultaneous determination of 2-aminofluorene and 2,7-diaminofluorene. The sensitivity of the determination can be enhanced substantially by adsorptive accumulation of analytes on carbon paste electrode in the pH range 10-12. The detection limits for the accumulation time 200s were evaluated as 2.10-7 and 1.10-7 mol L-1 for 2-aminofluorene and 2,7-diaminofluorene, respectively. Relative standard deviations for the concentration range 1-10 x 10-7 mol L-1 do not exceed 10%.
