摘要: A novel nano crystalline Ag₂O₂-PbO₂film chemically modified electrode (CME) was prepared and the CME was characterized by X-ray diffractometer (XRD) and atomic force microscope (AFM). By chronoamperometry, the nano Ag₂O₂-PbO₂ CME was used as bioelectrochemical sensor to determine the population of Escherichia coli (E. coli) in water. Compared with conventional methods, it is found that the technique we used is fast and convenient in counting E.coli.
