A PVC membrane based nickel(II) selective electrode was constructed using 11,14-diaza-4,7-dioxo-2(3),8(9)-dibenzoyl-cyclotetradeca-10,14(1)-diene (DADOCTD) as a neutral carrier. The sensor exhibits a Nernstian response for Ni(II) ions over a wide concentration range of 3.9 x 10-6 - 1.0 x 10-1 with a slope of 29.0 mV/decade. It has a relatively fast response time and can be used for 120 days without any considerable divergence in potentials. The proposed sensor revealed relatively good selectively and high sensitivity for Ni(II) over a bi-, tri- and tetravalent metal ions and could be used in a pH range of 3-8. It was successfully also used as an indicator electrode in potentiometer titration and in analysis of concentration of nickel in real samples.
