Abstract
The synthesis of poly(aniline-co-pyrrole)-Sn(IV)tungstoarsenate((PA-co-Ppy)-STA) nanocomposite cation exchange membrane was prepared through solution casting method in order to ensure the homogeneity of the obtained membrane. The synthesis of the membrane was confirmed by characterization of the nanocomposite membrane by various instrumentation techniques like Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray analysis (EDX), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD) and Thermogravimetric Analysis (TGA) techniques. The selective detection of Ni(II), having detection limit 1 x 10(-9)-1 x 10(-1) M, the range of pH 5-8 and response time 35 s. The analytical efficacy of this electrode was built up by utilizing it as an indicator in the potentiometric titration. Various experimental parameter studies proved the absorption of Ni(II) on nanocomposite. The method used is a classical method for fabrication of an ion selective electrode and hence is easier and cost effective, other than being most precise for the detection of Ni(II) ions. Along these lines, this novel effort may be a reliable and effective to detect Ni(II) in environmental and biomedical sector in a broad scale.
