A novel copper (II) selective sensor based on Dimethyl 4, 4′ (o-phenylene) bis(3-thioallophanate) in PVC matrix

Zinc Oxide Quantum Dots as Efficient Electron Mediator for Ultrasensitive and Selective Electrochemical Sensing of Mercury

“…The modulations of electrode require expert handling during fabrication and proper storage conditions like optimum temperature and pH. Furthermore, shelf life of such fabricated electrode is less [18][19][20][21][22][23].…”

A Novel Potentiometric Sensor Based on 1,2-Bis(N’-benzoylthioureido)benzene and Reduced Graphene Oxide for Determination of Lead (II) Cation in Raw Milk

“…Plasticizer affects the dielectric constant of membrane phase and also has a very important role in optimizing the physical properties of PVC membrane, as well as ensuring high mobility of ionophore and its complex in membrane [49]. In this study, we applied the DBP with low dielectric constant (ɛ=6.4) compared to some plasticizers with high dielectric constants such as 2-nitrophenyl octyl ether, oNPOE (ɛ=24) and nitrobenzene, NB (ɛ=36.1) as the results obtained by previous studies recommend the relatively non-polar plasticizer materials for improving membrane performance of mono-and bi-valent cation selective electrodes [50][51][52].…”

A simple and facile colorimetric chemosensor for selective detection of Cu2+ ion in aqueous solution

“…Consequently, a large number of papers involving colorimetric chemosensor [18][19][20][21][22][23], fluorescent chemosensor [24][25][26][27][28][29] and other techniques [30][31][32][33][34][35] have been published for metal ion detection. In recent themed issue series of Chemical Society Reviews on sensor targets and imaging agents also confined an exciting mix of reviews focusing on small organic or transition metal receptors.…”
