preparation of silver ion selective electrode using a new synthesized ligand as ionophore

Abstract: identification, measurement and separation of silver ion is important due to the manyapplications of this metal in various industries and medicine. another issue that makes silver important isthe poisoning caused by silver in the body. in this study, we are looking for a cheap, portable and highprecisionmethod to measure silver ions. the chosen method is the method of ion-selective electrodes(ise). the main point in the manufacture of ion-selective electrodes is the construction of the membrane.the constructed membrane includes an ionophore, ion additive, pvc and lubricant. the ligand used iswith n'-n'-n'-s (5-bermo-2-hydroxybenzylin) -2-2-dimethylpropane-3. benzyl acetate is used as alubricant and sodium tetra phenyl borate (natpb) is used as an ionic additive. in addition to the type ofmembrane components, its amount is also important for making an ion-selective electrode. pvc, ionicadditive, ligand, and lubricant are: 39, 3, 5, and 53 percent, respectively. the (ise) showed linear nernstresponses to ag+ ions in the range of 1.0 × 10-2 to 1.0 × 10-7 m the built ion selective electrode gives acorrect linear response in the shortest possible time in the presence of interfering ions and also in the rangeof ph range.
