“…However, using the acetate buffer is favored as it showed more stable and reproducible results which can be ascribed to the absence of hydroxide as the strongest interfering anion especially for iodide sensing 5. Moreover, we detected the different response characteristics at very low pH value (2.0) using phosphate buffer in order to minimize the hydroxide interference to the lowest value.…”

“…The selectivity manner of these sensors towards anions is found to be influenced by the steric effect related with the structure of ligands and the properties of the central metal ions 2–4 where a direct interaction occurs between the central metal of the membrane active components and the analyte anion. Several iodide selective electrodes have been reported in literature based on various metal complexes such as Cu 2+ 5, Hg 2+ , Cd 2+ 6, Ti 4+ 7, Co 3+ 8, Zn 2+ 9, Co 2+ 10, Fe 3+ 11, Mn 3+ 12, Ni 2+ 13, and Fe 2+ 14 in various matrices including polyvinyl chloride and carbon paste. To the best of our knowledge, there is only one published paper on the use of screen printed electrode for iodide determination 15.…”

[a] 1IntroductionIodide is necessary for human health as it guarantees the proper thyroid gland function and it is used as antiseptic for skin wounds.I odidea lso exists in food, drug compound and in drinking water and it is added to table salts as as upply of iodine to prevent iodine shortage disorders [1].I na ddition, it is used as catalyst or stabilizer in polymer production and as purifying agent of drinking and swimming pool waters. Therefore,d etermination of iodide in the field of food, biological, and environmental samples is of vital importance.F or this purpose,m any methods have been developed, among of them potentiometric basedi on selective electrode methodw hich offers speed determination, ease of preparation,f ast response time,w ide working linear range,f air selectivity,a nd low cost.Anion-selective electrodesb ased on lipophilic quaternary ammonium or phosphonium saltse xhibit Hofmeister selectivity pattern that is basedo na nionl ipophilicity. Thus,t he construction of anion potentiometric sensors based on new metal complexes which display non-Hofmeister selectivity pattern is an attractive pointo fr esearch in the field of chemical sensors.T he selectivity manner of theses ensors towards anions is found to be influenced by the steric effect related with the structure of ligandsa nd the properties of the central metal ions [2][3][4] where ad irect interaction occurs between the central metal of the membrane active components and the analyte anion. [14] in various matrices including polyvinyl chloride and carbon paste.T ot he best of our knowledge,t here is only one published paper on the use of screen printed electrode for iodided etermination [15]. Schiff bases are condensation products of primary amines with carbonyl compounds and they were first reported by Hugo Schiffi n1 864. Schiff bases have wide applications in foodi ndustry,d ye industry,a nalytical chemistry,c atalysis,f ungicidal, agrochemical and biological activities [16].T he transition metal complexes of Schiff-bases have been foundt os how attractive properties over the other ligands such as ease of preparation, formationo fh ighly lipophilic complexes,r emarkable biological and pharmacologicala pplications and the construction of different highly selective anion and environmental sensors,e nergy storage devices and solar cells [17][18][19][20].In this work, the synthesized Cu(II)-Schiff base complex (1) namely N-(4,6-Dimethyl-pyrimidin-2-yl)-4-[(2-hydroxybenzylidene)amino] benzene sulfonamidec opper-(II) dihydrated complex [21] (Fig.1)w as used as ionophore in polymeric membrane,c arbon paste,a nd screen printed electrodes.D ifferent compositions were studied, the selectivity behaviorw as examineda nd the electrodes were successfully applied for determination of iodide by ) and improved selectivity over the highly interfering thiocyanate were obtainedi nc omparisonw ith the previously reported Schiff base complexes-based iodide sensors.

“…Potansiyometrik yöntem, bu yöntemlerle kıyaslandığında, daha kısa analiz süresi, ekonomik olma, elektrotların kolay hazırlanabilmesi, kullanım pratikliği ve numunenin özelliğini bozmadan doğrudan ölçüm yapılabilmesi gibi pek çok açıdan üstünlük sağlayarak dikkatleri üzerine çekmektedir [17]. Bu amaçla kullanılacak iyon-seçici elektrotların (ISE) hazırlanmasında uzun yıllardır poli(vinil klorür)ün (PVC) destek malzemesi olarak kullanıldığı iç dolgu çözeltili PVC membran elektrotlar genellikle tercih edilmektedir [18].…”

Özet: Bu çalışmada, iyonofor olarak 5, 11,17,23-tetra(tert-bütil)-25,26,27,28-tetra(4-propilimidazol asetamit)-kaliks[4]aren bileşiğinin kullanıldığı iyodür-seçici yeni bir polivinil klorür (PVC) membran elektrot hazırlandı. İyodür -seçici membranın hazırlanmasında kullanılan PVC, o-nitrofeniloktileter (o-NPOE; plastikleştirici) ve iyonoforun oranı değiştirilerek, optimum membran bileşimi %2 iyonofor, %29,7 PVC, %68,3 o-NPOE olarak bulundu. pH 4,0'de elektrodun doğrusal çalışma aralığının ve eğiminin sırasıyla 1,0×10 -5 -1,0×10 -2 M ve 52,1± 2,6 mV/pI olduğu belirlendi. Önerilen elektrodun oldukça kısa bir cevap süresine (5-10 s) ve 5 ay'dan daha uzun bir ömre sahip olduğu gözlendi. Elektrot diğer anyonlar varlığında Abstract:In this study, a new iodide-selective polyvinyl chloride (PVC) membrane electrode using 5,11,17,23-tetra(tert-butyl)-25,26,27,28-tetra(4-propylimidazole acetamide)-calix[4]arene compound as an ionophore was prepared. Optimum membrane composition was found as 2% ionophore, 29.7% PVC and 68.3% onitrophenyl octyl ether (o-NPOE; plasticizer) by changing the ratio of ionophore, o-NPOE and PVC used in the preparation of membrane. The linear working range and the slope of the electrode at pH 4.0 were determined as 1.0×10 -5 -1.0×10 -2 M and 52.1± 2.6 mV/pI, respectively. It was observed that the proposed electrode had a short response time (5-10 s) and a lifetime of > 5 months. The electrode exhibited selectivity towards different anions in the order of I ->Salicylate> ClO4 -> NO3 -> SCN -≈ Benzoate > NO2 -> Br -> Cl -> F -> Citrate > HCOO -. Moreover, the proposed electrode was successfully used as an indicator electrode in the precipitation titration of iodide with silver nitrate.
