Abstract

PVC based ion selective electrode, which was selective and sensitive to Ni (II) ions, was developed using 1- phenyldecane - 1,3 - diones (LIX 54) as a carrier. The electrode exhibited a good potentiometric response for Ni (II) over a wide concentration range (1.0×10-5 – 1.0×10-1 M) with a slope 29.1 + 1.6 mV/decade. The proposed electrode has a response time about 25 s. The electrode is suitable for use in aqueous solutions in a wide pH range of 8.0 to 9.5. The proposed electrode was used in two different applications such as the determination of nickel concentration in nickel-cadmium battery and as an indicator electrode for potentiometric titration of Ni2+ion with EDTA.
