Electrochemical bio-sensor for degradation of phenol in the environment

Abstract

Bioelectrochemical systems based on bacteria thin film modified electrode were explored. The prepared bacteria modified aluminum electrode was characterized with voltametric methods, as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Electrochemical polarization curves.The proposed electrode indicated a definite redox response, high conductivity and electrochemical stability. The experimental results revealed that the prepared electrode could be a feasible for degradation of hazardous phenol pollutants. The sensor was successfully applied to the determination of phenol in a real sample with satisfactory results.
