Abstract

An anodically pretreated boron-doped diamond (BDD) electrode was used for the voltammetric and amperometric determination of the genotoxic pollutants 2-aminobiphenyl, 4-aminobiphenyl, 1-aminonaphthalene, and 2-aminonaphthalene. Their simultaneous voltammetric determination is only possible when the difference of the peak potentials of the particular analytes is higher than ca. 140mV. Their complete separation using high performance liquid chromatography (HPLC) with amperometric detection at a BDD film electrode in wall-jet arrangement results in limits of detection in the 10-8molL-1 concentration range and can be lowered to nanomolar concentrations, as demonstrated by their determination in azo dye sunset yellow using solid-phase extraction at Lichrolut EN cartridges.
