Abstract
Square wave voltammetry and differential pulse voltammetry have been used for the determination of 2-acetamidofluorene and fluoren-9-ol using carbon paste electrodes, following the study of the influence of the carbon paste composition on the voltammetric signals of the analytes. The methods are based on the oxidation of the above compounds and they include adsorptive accumulation of the analyte on the surface of the working electrode. The limit of detection was 1 μmol l-1 for fluoren-9-ol in a medium of 0.1 M H2SO4, and 40 nmol l-1 for 2-acetamidofluorene in Britton-Robinson buffer (pH 7).
