Effect of Various Deposition Techniques, Electrode Materials and Posttreatment with Tetrabutylammonium and Tetrabutylphosphonium Salts on the Electrochemical Behavior and Stability of Various Prussian Blue Modified Electrodes

摘要: The effect of various deposition techniques, electrode materials and posttreatment with tetrabutylammonium tetrabutylphosphonium salts on the electrochemical behavior stability Prussian blue (PB) modified electrodes, namely PB glassy carbon silicate-film supported PB-doped silicate ceramic electrodes using chemical is reported. Cyclic voltammetry amperometric measurements hydrogen peroxide were performed in a flow injection system while carrier phosphate buffer (pH 7.0) rate 0.8 mL min(-1) was propelled into through cell housing working as well an AgAgC.1, M KCl reference Pt auxiliary electrode. results showed that procedure, material additional chemicals can significantly alter film. Among studied those based film electropolymerized best stability. (Less)
