Abstract
Optimum 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.
