“…[22] This enables potentiometric performance that based on the exchange equilibrium process between the electrode and the sample solutions. [23] In another way, the neutral ionophores, such as βcyclodextrin, [24] phosphorated calix, [25] arene derivatives, [26] or valinomycin, [27] atropinium 5-nitrobarbiturate liquid membranes, [28] are taken into account to achieve better sensor performance, concerning especially the selectivity as well as a wide linear response.…”

This study presents an attempt has been carried out to fabricate ion‐selective electrodes (ISEs) for the determination of Atropine sulfate (AT) in pharmaceutical formulas. Three plasticizers; namely, di‐n‐butyl phthalate (DBP), bis (2‐ethyl hexyl) phthalate (BEP), nitrobenzene (NB), and tetrahydrofuran (THF) were used in the fabrication of the three ion selective electrodes after incorporating into polyvinyl chloride (PVC) and symbolized as E1, E2, and E3, respectively. Beyond evaluation of the three ISEs, it has been confirmed that one with DBP experienced the most Nernstian behaviour. For the electrode of interest, the slope and detection limit are 55.02 mV/decade and 1.1×10−6 M, respectively. The linear range was 1.0×10−2–1.0×10−5 M (R2=0.9999) with recording 5 s and 45 days; sequentially, for the response time and shelf life of E1 electrode. The sensor has experienced high selectivity for atropine sulfate, verifying from the selectivity coefficient data for a number of potential interferences. The statistical analysis using t‐test and F‐test indicates the eligibility of constructed electrode for utilization in field of pharmaceutical analysis. A satisfactory accordance has been obtained between the proposed electrode for atropine sulfate and the standard method. This methodology is supposed to be applicable in quality control and even clinical diagnosis.

“…However, the amount of Ch ISEs is still inadequate. An ion-selective Ch electrode based on a membrane containing a valinomycin derivative for the determination of a cholinergic agent showed excellent sensitivity from 2 × 10 −8 -10 −4 M [25], and a novel Ch ISE for concentration analyses in milk powder and infant formulas exhibited a low detection limit of 0.061 µM [26]. Nevertheless, the excellent properties relied on the internal filling solution containing a high concentration of Ch bromide or hydrophilic (water-soluble) p-sulfonated calixarene, increasing the difficulty to miniaturize and store.…”

Protoporphyrin IX-based all-solid-state choline (Ch) ion-selective electrodes (ISEs) were fabricated and characterized. Poly (3,4-ethylene dioxythiophene) doped with poly (styrene sulfonate) (PEDOT/PSS) functioning as an ion-to-electron transducer was electropolymerized on the gold wire (0.5 mm diameter). The conductive polymer was covered with a Ch selective membrane containing protoporphyrin IX as an ionophore, which exhibited a lower detection limit of 0.49 μM with the potentiometric method. The Ch sensor performed a wide linear range from 1 μM to 1 mM, a fast response time of less than 5 s, and a decent selectivity of common inorganic and organic ions in the human body. Characteristics such as pH and temperature stability, life span, reproducibility and repeatability were also investigated to be satisfied. With the background of artificial cerebrospinal fluid, the recovery rate in 10−5 M of Ch solution was measured by the standard addition method, revealing the potential for biological application.

“…Some of them were based on the tetraphenylborate (TPB) salts. [3][4][5][6][7] Some other electrodes were based on different atropine-ionophores, like calix [6]arene, 8 valinomycin, 9 or charged ionophores, like o-phenylenediamine copolymer, 10 atropine-picrolinate and atropinium 5-nitrobarbiturate liquid membranes, 11 or atropine-reineckate. 12 All of the aforementioned electrodes were applied for atropine determination.…”
