Phenol biosensors in environmental engineering

Abstract

Phenol measurement performance of three different horseradish peroxidase-based enzyme electrodes was studied. Electrode A was operated in a flow-injection system, while Electrode B and C were used in batch experiments. Various phenolic compounds were tested at each electrode. The highest sensitivity was observed for the biosensor fabricated by Electrode A, which can measure lower phenol concentrations. Although the same enzyme was used, each working electrode gave response to different phenolics by different selectivity depending on electrode configuration. However, Electrode A, B, and C gave no response to phenol, catechol, and o-cresol, respectively.
