摘要：

A gas biosensor for vapors of phenolic compounds, comprising an enzyme/gas-diffusion electrode with tyrosinase enzyme is investigated. The transient amperometric signal and the calibration curves of this gas biosensor are studied in the presence of phenol, p-cresol and 4-chlorphenol vapors. It is shown that phenol vapor concentrations in the ppb range are detectable with this type of gas biosensor. The stable steady-state performance of the biosensor allow the measurement of the electrochemical impedance of the system in a broad frequency range (50 kHz to 1 mHz). (C) 1997 Elsevier Science S.A.
