“…Outside this range, the electrode response changed drastically and no Nernstian relationship was observed. The obtained changes of potential at lower (< pH 2) and higher (> pH 6) pH values could be due to the protonation of the ionophore and formation of some hydroxy complexes of Ag þ ion in solution, respectively [23,51,54,67]. In this study, all measurements were made at pH 4.3.…”

A new PVC membrane potentiometric sensor for Ag(I) ion based on a recently synthesized calix[4]arene compound of 5,11,17,23-tetra-tert-butyl-25,27-dihydroxy-calix[4]arene-thiacrown-4 is developed. The electrode exhibits a Nernstian response for Ag(I) ions over a wide concentration range (1.0 Â 10 À2 À 1.0 Â 10 À6 M) with a slope of 53.8 AE 1.6 mV per decade. It has a relatively fast response time (5 -10 s) and can be used for at least 2 months without any considerable divergence in potentials.

“…Furthermore, the sensor may also be affected due to interference of the hydrogen ions. 35 At the elevated pH, the iron(III) concentration in solution was dramatically reduced, which may be due to the formation of iron(III) hydroxo complexes, and the magnitude of the voltage change can be reconciled with iron(III) speciation calculations in solution.…”

A novel poly(vinylchloride)-based membrane sensor using N −6 M. The proposed ion selective electrode showed fast response time (< 15 s), wide pH range (3.0-7.0), high non-aqueous tolerance (up to 20%) and adequate long life time (120 days). It also exhibited very good selectivity for Fe 3+ relative to a wide variety of alkali, alkaline earth, transition and heavy metal ions. Further, the analytical applicability of the sensor was tested as an indicator electrode in the potentiometric titration of Fe 3+ with EDTA.

“…It is well known that the sensitivity and selectivity obtained for a given ion-selective electrode depends not only on the nature of ionophore used, but also significantly on the membrane composition and the properties of the plasticizer employed [16][17][18][19][20]. Thus the influences of the membrane composition and the nature of plasticizer on the response characteristics of Fe(III) ion-selective electrode based on DEDIO were investigated and the results summarized in Table 1.…”

ABSTRACT. A potentiometric iron sensor based on the use 3-(2-diethylamino-ethylimino)-1,3-dihydro-indol-2-one (DEDIO) as an ionophore in poly(vinyl chloride) (PVC) matrix, is reported. The plasticized membrane sensor exhibits a Nernstian response for Fe(III) ions over a wide concentration range (2.0 × 10 -6 -5.0 × 10 -2 M) with a super Nernstian slope of 26(±1) mV per decade. It has a fast response time of <12 s and can be used for ten weeks without any considerable divergences in its potentials .the electrode can be used in the pH range 4.5-8.0. The proposed sensor shows fairly good discriminating ability towards Fe(III) ion in comparison with a large number of alkali, alkaline earth, transition and heavy metal ions. The sensor was used as indicator electrode in potentiometric titration of Fe(III) ions vs. EDTA.
