Effect of Precipitating Media on the Response Behaviour of Ni(II) Ion-Selective Electrode
Author(s): Krishna Badan Nakarmi and Amar Prasad Yadav
Abstract: Ni(II) being a toxic heavy metal and an environmental pollutant, its monitoring is a matter of great interest to researchers. Among various methods to monitor nickel in environment, Ion-Selective Electrode is currently on rise due its low cost, simplicity and reliability for onsite measurement. This study introduces a new method for the preparation of Ni(II) ion-selective electrode by co-precipitating NiS and Ag2S in strong alkaline medium in 1:2 mass ratio (NiA1). The results have been compared with the sensor prepared by traditional simple co-precipitation method (NiS1), which has been reported to be not suitable method. The prepared Ni-ISEs are characterized for its phase and morphology by using X-ray diffractometer and scanning electron microscope. Potentiometric characterization has been done with respect to pH stability, Nernstian response, and potentiometric titration. The results show new method as good alternative for preparing Ni(II) ion-selective electrode and NiA1 performs better than NiS1.
