2-amino-n-benzthioazolyl benzamide (abtb) was synthesized, characterized and used for thefabrication of a potentiometric sensor for cu2+ metal ions. the electrode exhibits linear response to cu(ii) over a wide concentration range (4.79×10 -8 – 1.85×10 -1 m) with nernstian slope of 30 ± 1.5 mvper decade. the electrode can be used in the ph range from 2 to 9. it has a fast response time of about1...

A theory for the interpretation of the operation mechanism of ion-selective membrane electrodes is briefly outlined. The statements are based on the accumulated results concerning the electrochemical and spectrochemical behaviour of ion-selective membranes.

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. Th...

A hydrogen ion-selective poly(vinyl chloride) membrane electrode was constructed using 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetracyanomethoxycalix[4]arene as a neutral carrier. The electrode showed an apparent Nernstian response in the 2-11.5 pH range with a slope of 54.0 +/- 0.2 mV/pH at 20 +/- degrees C. This electrode showed a rapid response of the emf to changes in the pH, high ion selec...

A highly selective copper (II) coated graphite sensor was prepared by 1,13-bis(8-quinolyl)- 1,4,7,10,13-pentaoxatridecane (kryptofix 5) as a supramolecule ionophore into plasticized polyvinyl chloride (PVC) membrane. The best response characteristic was observed using the membrane composition of PVC = 30.0 mg, dioctyl sebacate (DOS) = 63.5 mg, palmitic acid (PA) = 3.0 mg and kryptofix 5 = 3.5 m...

The design and properties of novel type of solid-contact ionophore-based ion-selective microelectrodes are reported. The microelectrode is based on an insulated needle-shaped metallic wire with an exposed apex. The ion-to-electron transducer is made of poly(3-octylthiophene-2,5-diyl) and placed between an ion-selective membrane and the metallic tip. The ion-selective polyvinyl chloride-based me...

Calibration-free coulometric determination of K+ ions was realized using an all-solid-state thin-layer laminated cell with a simple laminate structure. The fabricated consists Ag/AgCl electrode, plastic spacer for positioning the aqueous sample solution, organic ion-selective membrane, and conducting polymer/carbon electrode. An originally prepared conducting-polymer-dispersed ink cast on condu...
