The electrochemical sensor based on electrochemical oxidation of nitrite on metalloporphyrin–graphene modified glassy carbon electrode

Abstract

In this study, 5-(4-aminophenyl)-10,15,20-triphenylporphyrin]Mn(iii) (MnNH2TPP) and graphene oxide (GO) composite materials (GO–MnNH2TPP) were successfully used to modify a glassy carbon electrode (GC) by the drop casting method.
