Sažetak
A poly (vinyl chloride)-based membrane of 2,9-dihydroxy-1,10-diphenoxy-4,7-dithiadecane
(C20H26O4S2) as a neutral carrier was prepared and investigated as an Y3+-selective electrode. Effects of various
plasticizers and anion excluders were studied in detail and improved performance was observed. The best
performance was obtained for the membrane sensor having a composition of L: PVC: NPOE: PA in the ratio
of 2:30:62:6 (mg). The performance of the membrane was found to be the following: A Nernstian slope of
20.0 ± 0.2 mV per decade across a broad range (1.0 × 10−9 to 1.0 × 10−1 mol dm–3); a detection limit of
2.14 × 10–10 mol dm–3 between the pH = 4.5 and 9.0; additionally, the response time was about 15 s; good
Y3+ selectivity over a wide variety of other metal ions. The membrane sensor was applied as an indicator
electrode in potentiometric titration of fluoride ion and also used for determination of F− ion in tap water
and toothpaste samples. (doi: 10.5562/cca1937)
