Voltammetric Determination of 1-Nitropyrene and 1-Aminopyrene at a Boron-Doped Diamond Film Electrode
AbstraktOptimum conditions for the determination of carcinogenic 1-nitropyrene (NP) and 1-aminopyrene (AP) by differential pulse voltammetry with a boron-doped diamond film electrode were found − aqueous-methanolic (3:7) Britton-Robinson buffer (pH 3), scan rate 20 mV s−1, pulse duration 100 ms, pulse amplitude −50 mV (NP) and 50 mV (AP). The regeneration in NP determination was carried out before analysis by switching fifty-times between the potentials 800 mV and −500 mV every 0.3 s. In determination of AP, no regeneration was needed. The limits of quantification were 8•10−7 and 2•10−7 mol dm−3 for NP and AP, respectively.
