It is necessary to synthesize new material for the advancements of the technology. In this study, new and novel poly(2-anisidine)@Zirconium tungstate (cas 16853-74-0) (P2A/ZrW2O8) was synthesized by simple so-gel method. Physicochemical characterization of P2A/ZrW2O8 was done by thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ion exchange and simultaneous four probe dc conductivity studies. The conductivity study revealed its highly semiconducting nature, in the range of 10− 1–10− 2 S·cm− 1. Ion-exchange capabilities of the composite make it applicable for cation-exchange studies. The result of distribution studies (Kd) revealed its selectivity towards Cd2 + compared to other metal ions. This property of the composite was utilized for designing Cd2 + selective membrane electrode. Several important physical parameters of the ion-selective electrode were determined, such as Nernstian slope (32.32 mV·decade− 1), working pH range was 2.0–4.0 and response time was found ~ 17 s. The analytical utility of this wave like composite membrane electrode was as, indicator electrode in various potentiometric titrations.
