A new potentiometric thiocyanate-selective membrane sensor based on salicyladehyde-o-aminophenol binuclear copper (II) [Cu2(II)-SOA] complex as a neutral carrier is reported, which displays a preferential potentiometric response to thiocyanate ion and an anti-Hofmeister selectivity sequence in the following order: SCN- > Sal- > ClO4- > I- > NO2- > Br- > Cl- > NO3- > SO32- > H2PO4- > SO42- . The sensor exhibits a near-Nernstian potential over a wide linear range of 6.0×10-7 - 1.0×10-1 M with a detection limit of 2.0×10-7 M and a slope of –56.2 mV/decade in pH 4.0 of a phosphate buffer solution at 20 °C.

A plasticized poly(vinyl chloride) membrane electrode based on 4-[(5-mercapto-1,3,4-thiadiazol-2-ylimino)methyl]benzene-1,3-diol (L) for highly selective determination of palladium(II) (in PdCl42– form) is developed. The electrode showed a good Nernstian response (29.6 ± 0.4 mV per decade) over a wide concentration range (3.1 × 10–7 to 1.0 × 10–2 mol l–1). The limit of detection was 1.5 × 10–7 mol l–1. The electrode has a response time of about 20 s, and it can be used for at least 2 months without observing any considerable deviation from Nernstian response. The proposed electrode could be used in the pH range of 2.5–5.5. The practical utility of the electrode has been demonstrated by its use for the estimation of palladium content in aqueous samples.
