A new nanocomposite of graphene oxide (GO) functionalized with polyaniline (PANI) doped with silver was synthesized. The monomer was oxidized on the surface of the graphene oxide afterward was treated with the silver nitrate solution. The composite polyaniline@graphene oxide/Ag (PANI@GO/Ag) was subjected to the characterization with various spectrophotometric instrumental methods such as, SEM-EDX, TGA, FTIR, UV–vis etc. The four probe electrical conductivity of the PANI@GO/Ag was determined that showed its semiconductor nature. Cyclic and isothermal conductivity study of the composite was shown excellent results in the perspective of strong material. The property of the composite was cashed for the designing of ion sensitive membrane electrode for Cd²⁺ heavy metal from the waste water. Different physical parameters of ion-sensitive membrane electrode such as, Nernstian slope (26.20 mV/decade conc change); working pH range (2–6); response time (15 s) was determined. The analytical utility of this composite ion sensitive membrane as an indicator electrode in different titrations for municipal wastewater.
