NOVELTY - Application of Hemin-graphene/poly(3,4-ethylenedioxy-thiophene) ternary complex as modified biosensor electrode material for determining hydrogen peroxide, is claimed. The ternary complex contains 14-30 %mass graphene and 1-10 %mass poly(3,4-ethylenedioxy-thiophene). The content of reduced graphene oxide is 60-84 %mass. USE - Application of Hemin-graphene/poly(3,4-ethylenedioxy-thiophene) ternary complex as modified biosensor electrode material for determining hydrogen peroxide. ADVANTAGE - The ternary complex enables efficient, quick and accurate determination of hydrogen peroxide by simple method, when used as modified electrode material. The usage of toxic reagent is eliminated.
