Sažetak:
S, S'-bis(2-aminophenyl)ethanebis(thioate) (APhET) was synthesized and used as ion carrier in the fabrication of copper(II) ion selective PVC membrane electrodes. The best performances are obtained by a membrane electrode having composition: PVC as matrix (66 mg), APhET as ionophore (4 mg), o-NPOE as plasticizer (132 mg) and NaTBP as anionic additive (1/2 mole ratio in respect to APhET). This electrode shows a linear potential response to copper(II) in concentration range 6.0×10-6 - 5.0×10-2 moldm-3, with Nernstian slope of 29.5 mV/decade and detection limit down to 4×10-6 moldm-3. It is suitable for copper(II) determinations within pH between 4 and 7, and work well over a period of 3 months. The electrode is selective for copper over a large number of metal ions, except Hg2+. There were no noticed any interference by chlorides and other examined anions. Described membrane electrode can be used in analytical measurements by direct potentiometry as well in potentiometric titration.
