Voltammetric Determination of Trace Amounts of 2-Aminofluoren-9-one with Preconcentration of the Analyte by Solid-Phase Extraction

Abstract

Optimum conditions were found for the determination of nanomolar and subnanomolar concentrations of genotoxic 2-aminofluoren-9-one (2-AFN) by adsorptive stripping differential pulse voltammetry (AdSDPV) at a hanging mercury drop minielectrode (HMDmE) after preliminary separation and preconcentration by solidphase extraction (SPE) in LiChrolut RP-18 E (500 mg) columns.
