PEROXIDASE-MIMETIC SENSOR FOR DETECTION OF ETHANOL IN LOW CONCENTRATIONS IN AQUEOUS SOLUTIONS... [Pg.302]

As shown below, the basic principles of peroxidase-mimetic sensor appliance operation are developed using the example of model peroxidase reaction of ethyl alcohol electrochemical oxidation to aldehyde. [Pg.302]

Studies on ethanol trace detection in aqueous solutions were carried out in an electrochemical cell of peroxidase-mimetic sensor of the potentiometric type, consisting of a reference electrode (Ag/AgCl) and a biomimetic electrode. Redistilled water was used for the background solution. The biomimetic electrode was prepared by adhering hematin-containing meroxidase mimetic to aluminum foil with Pattex adhesive [7, 8],... [Pg.302]

To check these suggestions, the authors conducted an experiment with a peroxidase-mimetic sensor prepared on a new aluminum electrode under conditions corresponding to one of the minima in Figure 8.14. As shown by the plot of this experiment (point A in Figure 8.14), the minimum at C2H5OH concentration equal 10-3wt.% depends on aluminum foil conditions for a fresh electrode a sharp, jump-like increase of the potential is detected. [Pg.306]

The investigations of catalase-mimetic sensors allow continuation of studies in the field of biomimetic sensors of peroxidase type. [Pg.302]
