Abstract :In this study, a new film electrode for determination of hydrogen peroxide was developed. Polypyrrole-poly insert ignore into journalissuearticles values(sodium-4-styrenesulphonate); film have been prepared on the platinum electrode by the electropolymerization of pyrrole was carried out in the presence of polyinsert ignore into journalissuearticles values(sodium-4-styrenesulphonate);. Optimum conditions of polypyrrole-polyinsert ignore into journalissuearticles values(sodium-4-styrenesulphonate); film was founded. Oxidation of the hydrogen peroxide was examined at a different potential . Therefore, four different potentials insert ignore into journalissuearticles values(0.4, 0.5, 0.6, and 0.7 V); were determined. Also, concentration of pyrrole and polyinsert ignore into journalissuearticles values(sodium-4-styrenesulphonate); were examined. The effect of the number of cycles in their sensitivity to hydrogen peroxide is investigated. Morphology of electrodes was qualified by means of SEM. Free enzyme work was performed using the prepared film electrode and glucose oxidase. Linear increases were observed in the amperometric response currents of the electrode versus increasing glucose concentrations. It was shown that this film can be used for hydrogen peroxide producing enzymes.
