| Özet |
| In this study, poly(vinly chloride) (PVC) membrane ion–selective electrodes for the determination of zinc(II) ions were prepared using potassium hydrotris(N-tert-butyl-2-thioimidazolyl)borate (L1), 1-[Bis(dimethylamino)methylen]-5-chlorobenzotriazolium-3-oxide hexafluorophosphate (L2), 1,4,8,12-tetraazacyclopentadecane (L3) and tetrabutylthiuram disulphide (L4) ionophores. Based on potentiometric performance properties, the optimum membrane composition was determined as 8.0% tetrabutylthiuram disulphide (L4), 58.0% o–nitrophenyloctylether (o–NPOE), 33.5% PVC and 0.5% potassium tetrakis (p–chlorophenyl) borate (KTpClPB). The electrode exhibits a wide concentration range from 1.0 × 10−5 to 1.0 × 10−1 M, and has a detection limit of 6.50 × 10−6 M. The proposed electrode has a very quickly response time of 5s, good repeatability and selectivity. In addition, the electrode works in the wide pH range of 5.0–10.0 without being affected by pH changes. Finally, the developed zinc(II)–selective electrode was successfully used for the determination of zinc(II) in a drug sample. |
