“…Thus, Schiff bases offer a good possibility to be used as Ni 2+ selective ionophore. PVC-based membranes of meso-tetrakis-4-tris-(4-allyl dimethylsilylphenyl)silyl-phenylporphyrin (I) and (sal) 2 trien (II) [33], Ni (II) selective sensors based on Schiff bases membranes [34] have been studied as Ni 2+ selective sensors and the results reported in the present communication show that they perform well and could be used for its selective quantification.

PVC-based membranes of sulfamethoxazole diazonium resorcinol (SDR) as electroactive material with dioctylphthalate (DOP), Dioctylsebacate (DOS), o-Nitroph enyloctylether (o-NPOE) as plasticizing solvent mediators have been found to act as Ni 2+ selective sensor, the best performance was obtained with the sensor having a membrane of composition plasticizer:PVC:ionophore in the ratio 200:100:5 mg. The sensor exhibits Nernstian response in the activity range 5×10 −6 to 1.0×10 −1 M, performs satisfactorily over a wide pH range (5-9), with a fast response time (10 s). The sensor was found to work satisfactorily in partially different internal solution concentrations and could be used over a period of 2 months. Potentiometric selectivity coefficients determined by matched potential method (MPM) indicate excellent selectivity for Ni 2+ ions. The sensors could be used successfully in the estimation of nickel as an indicator electrode in potentiometric titration.

“…This is probably because the membrane components should exhibit low leaching into the sample solutions. Despite this, some authors have succeeded in using plasticized polymeric membrane ISEs for determining metal ions [4–24], alkaline and alkaline-earth ions [25], monohydrogen phosphate [26], chromate ions [27] and surfactants [28,29] in mixed solvents.…”

The construction and characterization of a new ion-selective electrode for the determination of the antipsychotic ziprasidone in mixed solvents is presented. The electrode contains a plasticized polymeric membrane based on a ziprasidone-tetraphenylborate ion-exchanger. The influence of membrane composition on the electrode response towards ziprasidone in hydroalcoholic solutions was studied. The electrode displayed a stable response in a 2:3 (v/v) methanol/water medium from a ziprasidone concentration of 3 × 10−6 M with a fast response time of less than 20 s. The electrode also showed good selectivity towards ziprasidone over common inorganic and organic compounds and several species with pharmacological activity. The electrode was successfully applied to the determination of ziprasidone in pharmaceuticals and human urine and serum.
