“…Such larger value is aroused from the (1 − 2 Z B ) in the Nicolsky-Eisenman equation. Hence, the smaller the charge of the interference ion, Z B, the larger the value of logarithm selectivity coefficient [1]. Furthermore, potassium and sodium ions have larger ionic radius and different chemical properties from copper (II) ion as potassium and sodium ions belong to alkali metal ion whereas copper (II) ion is a heavy metal ion, the disturbance produced by these two ions is negligible.…”

A screen-printed copper ion sensor with photocurable poly(n-butyl acrylate) (pBA) membrane based on ionophore o-xylylene bis(N,N-diisobutyldithiocarbamate) (o-xc) was successfully fabricated. Poly(2-hydroxylethyl methacrylate) (pHEMA)-modified Ag/AgCl screen-printed electrode was used in the development of the sensor and the sensor was characterized by potentiometric method. Optimization of pBA membrane for the electrode was carried out by varying the compositions of sodium tetrakis [3,5-bis(trifluoromethyl)phenyl]borate (NaTFPB) and o-xc to determine the best analytical performance. The addition of NaTFPB and the increment of its ratio relative to o-xc showed super-Nernstian, small linear range, and high detection limit. For sensor fabricated based on o-xc without the addition of NaTFPB, the sensor showed Nernstian response. The best optimized sensor showed Nernstian slope with 31.29 mV/decade over a wide linear range of 1.0 × 10 -2 -1.0 × 10 -6 M and low detection limit of 1.89 × 10 -7 M. The sensitivity of this sensor was also improved over the other copper ion sensors fabricated by similar photocuring technique. In addition, based on the separate solution method (SSM), this sensor exhibited good selectivity towards copper ion with low logarithm selectivity coefficient value for monovalent and divalent cations namely K Keywords: screen-printed copper ion sensor, photocurable poly(n-butyl acrylate) membrane, ionophore o-xylylene bis(N,Ndiisobutyldithiocarbamate), potentiometry Abstrak Sensor ion kuprum bercetak skrin yang berasaskan kepada ionofor o-xililen bis(N,N-diisobutilditiokarbamat) (o-xc) dalam membran terawatfoto poli(butil-akrilat) (pBA) telah dibangunkan.

“…Thus, two new ionophores, diphenyl amine (DPA) and triphenyl amine (TPA), were designed and synthesized to explore their sensing properties by potentiometric methods. Potentiometry offers an advantage over other electrochemical methods in terms of cost, sensitivity, and selectivity [5][6][7]. The results indicated strong affinity for Zn 2+ ions in case of DPA, while TPA was selective towards Ni 2+ ions.…”

“…A large number of receptors based on pyrroles, lactams, aliphatic amines, hydrazines and urea have been reported where the amine group (-NH-) acts as the anion or cation binding site [2][3][4][5][6]. Selectivity of the ionphore to act as acation sensor depends upon availability of the electron pair on nitrogen and the pre-organisation of the cavity size, while anion sensing is governed by chemical interactions [2][3][4].…”

Abstract:Two receptor molecules N-(2-nitrophenyl)benzene-1,2-diamine (DPA) and N,N-bis(2-nitrophenyl)benzene-1,2-diamine (TPA) are proposed as Zn 2+ and Ni 2+ -selective electrodes, respectively. The two electrodes respond to Zn 2+ and Ni 2+ ions with the detection limits of 1.3 × 10 −6 M and 2.8 × 10 −6 M, respectively. Both the electrodes have a life time of four months and respond within 15 s and 20 s, respectively, for Zn 2+ and Ni 2+ over a wide pH range (3-9). The electrodes show very good selectivity towards the primary ions in presence of some alkali, alkaline earth, and transition metal ions.

“…Accordingly, the safe limit of Cu 2+ is 1.3 ppm (∼20 M) in drinking water recommended by U.S. Environmental Protection Agency (EPA) [5]. The common analytical methods adopted for Cu 2+ measurement include atomic emission spectrometry (AES) [6], atomic absorption spectrometry (AAS) [7], inductively coupled plasma mass spectrometry (ICP-MS) [8] and electrochemistry assay [9]. In spite of high selectivity and sensitivity, these methods often require professional operational skills, tedious sample pretreatments and a long analysis time.…”

h i g h l i g h t s• A fluorescent probe for Cu 2+ has been developed by FITC functionalized gold nanoparticles.• Cysteine could replace FITC from the surfaces of gold nanoparticles and Cu 2+ could catalyze O 2 oxidation of cysteine.• The fluorescent probe provides high sensitivity toward Cu 2+ in drinking water as a real sample. g r a p h i c a l a b s t r a c t could catalyze O 2 oxidation of cysteine, and the generated disulfide cystine could not remove FITC from AuNPs' surface. Therefore, the recovery of fluorescence intensity was much weaker when compared with that of in the absence of Cu 2+ . And on the basis of this principle the concentration of Cu 2+ could be detected quantitatively. Under optimal conditions, our method exhibited high selectivity toward Cu 2+ and provided a good linear relationship in the range of 1.0-17.0 nM with the detection limit of 0.37 nM calculated by 3 /S. Furthermore, complicated synthetic procedures and poor water solubility could be ignored in this proposed fluorescent sensor.
