Zinc(II)-selective PVC membrane potentiometric sensor for analysis of Zn<sup>2+</sup>in drug sample and different environmental samples

In this study, a novel all-solid-state contact poly(vinylchloride) (PVC) membrane potassium selective sensor with a pyrazole derivative molecule as an ionophore has been developed. The potassium selective sensor has a composition of PVC, ionophore, anion excluder (potassium tetrakis (p-chlorophenyl)borat (KTpClPB)) and plasticizer (bis(2ethylhexyl)adipate (DEHA)) in the ratio of 32.0:4.0:1.0:63.0 (mg). The potassium selective sensor works in a linear concentration range of 1.0×10 -5 to 1.0×10 -1 M with a low detection limit of 6.02 × 10 −6 M The developed potassium selective sensor works in pH range of 6.0-10.0 and has good repeatability, selectivity and a short response time of 10 seconds. Finally, the developed potassium selective sensor was successfully used in the determination of potassium in tap water and a drug sample. Bu çalışmada, pirazol türevi bir molekülünün iyonofor olarak kullanıldığı yeni tümüyle katı hal kontak poli(vinilklorür) (PVC) membran potasyum sensörü geliştirildi. Potasyum seçici sensör PVC, iyonofor, potasyum tetrakis (p-klorofenil)borat (KTpClPB)) ve plastikleştirici (bis (2-etilheksil)adipat (DEHA))'ın 32.0:4.0:1.0:63.0 (mg)'lık bileşimine sahiptir. Geliştirilen potasyum seçici sensör, 6.02×10 -6 M'lık düşük algılama limiti ile 1.0×10 -5 -1.0×10 -1 M konsantrasyon aralığında doğrusal olarak çalışmaktadır. Geliştirilen potasyum seçici sensör pH 6.0-10.0 aralığında çalışmaktadır, iyi tekrarlanabilirlik, iyi seçicilik ve 10 saniyelik kısa cevap zamanına sahiptir. Son olarak, geliştirilen potasyum seçici sensör musluk suyu ve ilaç örneğinde potasyum tayininde başarıyla kullanılmıştır.

The first, novel solid-state membrane sensor for Zn(II) determination is developed based on ZnS nanoparticles. ZnS nanoparticles are synthesized by chemical co-precipitation and investigated via X-ray diffraction, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and impedance study. X-ray diffraction shows that the prepared ZnS nanoparticles have an average domain size of 5.72 nm, which is very close to the particle size obtained from TEM observations (6.30 nm). The ZnS nanoparticles are pressed into disks and examined as electroactive solid-state membrane. Solid-state membrane and coated wire sensors are fabricated. They display linear responses over concentration ranges of 1.0 × 10−5 to 1.0 × 10−1 mol L−1 Zn2+ ions with cationic slopes of 28.9±0.2 and 25.9±0.2 mV decade−1 for the solid-state membrane and coated wire sensors, respectively. The lower limits of detection are 2.86 × 10−6 and 4.60 × 10−6 mol L−1 Zn2+ ions for the solid-state membrane and coated wire sensors, respectively. The response time for the two sensors is instantaneous (1 s), and the useful lifetimes for the solid-state membrane and coated wire sensors are long (10 and 6 months, respectively). The solid-state membrane sensor is utilized for the quantification of Zn(II) ions in brass alloys and pharmaceutical preparations.

A novel poly(vinyl chloride; PVC) membrane‐based Cu(II)–selective sensor has been developed using synthesized 5,10,15,20‐tetrakis(4‐methoxycarbonylphenyl)porphyrin as an ionophore. The Cu(II)–selective sensor exhibits a Nernstian response for Cu(II) ion over a wide concentration range of 1.0 × 10−5 to 1.0 × 10−1 mol L−1 with the slope of 27.0 ± 2.5 mV/decade, and a lower limit of detection of 1.88 × 10−6 mol L−1. The novel sensor shows good repeatability and high selectivity for Cu(II) ions over other mono‐, bi‐ and trivalent cations. The sensor potential response remains unaffected by pH in the range of 4.4–10.6 and exhibits a fast response time of less than 10s. Finally the developed Cu(II)–selective sensor has been successfully used as an indicator electrode in the potentiometric titration of Cu2+ against ethylenediaminetetraacetic acid and also in the determination of Cu(II) ion concentration in different water and beverage samples.
