Abstract
This work is focused on the application of a silver solid electrode (AgE) for the development of modern voltammetric methods for the determination of submicromolar concentrations of biologically active compounds present in the environment. 8-Nitroquinoline (8-NQ), a well-known chemical carcinogen, was chosen as a model substance. Differential pulse voltammetry (DPV) was used to study electrochemical behavior of 8-NQ in different aqueous matrices. The following optimal conditions for determination of 8-NQ in the concentration ranges from 2 to 100μmolL-1 were used: Britton-Robinson (BR) buffer of pH3.0, the regeneration potentials cycles (Ein=-1000mV, Efin=-100mV) and constant cleaning potential -2000mV. Practical applicability of AgE for the determination of micromolar concentrations of 8-NQ was verified on model samples of drinking and river water.
