“…A comparison of the characteristics of the presently developed sensor with that of some of the reported sensors is presented in Table 5. An examination of the Table reveals that the proposed sensor is superior in terms of working concentration range [5-8, 10, 12, 15, 16], slope [5-8, 14, 15], life time [5,7,8,10,12] and pH range [5-8, 12, 14, 16]. In addition, the developed sensor can be used in the determination of Ni (II) in real samples -wastewater from electroplating plants and chocolates.…”

“…Conventional methods, such as the gravimetric method using dimethylglyoxime [3] or the spectrophotometric method [4], are not only time-consuming but also have some practical inconveniences. Although a number of ionselective electrodes have been reported in the literature [5][6][7][8][9][10][11][12][13][14][15][16], most of them suffer from one or more drawbacks.…”

Abstract.A new PVC membrane sensor, which is highly selective towards Ni (II) ions, has been developed using a thiophene-derivative Schiff base as the ionophore. The best performance was exhibited by the membrane having the composition percentage ratio of 5:3:61:31 (ionophore:NaTPB:DBP:PVC) (w=w), where NaTPB is the anion excluder, sodium tetraphenylborate and DBP is the plasticizing agent (dibutyl phthalate). The membrane exhibited a good Nernstian response for nickel ions over the concentration range of 1.0Â10 À1 -5.0Â10 À6 M (limit of detection is 1.8Â10 À6 M) with a slope of 29.5 AE 1.0 mV per decade of activity. It has a fast response time of <20 s and can be used for a period of 4 months with good reproducibility. The sensor is suitable for use in aqueous solutions of a wide pH range of 3.2-7.9. The sensor shows high selectivity to nickel ions over a large number of mono-, bi-and trivalent cations. It has been successfully used as an indicator electrode in the potentiometric titration of nickel ions against EDTA and also for direct determination of nickel content in real samples -wastewater samples from electroplating industries and Indian chocolates.

“…There are a number of reports in literature where analytical techniques such as atomic absorption spectrometry, voltammetry, atomic emission, and UV-Vis spectroscopy have been used for the detection of trace amounts of zinc [18][19][20][21][22][23][24][25][26][27][28][29][30] and nickel ions [31][32][33][34][35]. However, potentiometry, due to due to its inexpensive, wide, and linear range, is a fast and a simple procedure that has an advantage.…”

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.

“…electroreduction of CO 2 [4] and NO 2 - [5], epoxidation of olefins [6], chemical and electrochemical reduction of alkyl halides [7], medical diagnosis as contrast media for NMR imaging [8] and in the fabrication of ionselective membrane electrodes [9]. The ion-selective electrodes reported for the determination of Ni 2+ in literature till date has poor selectivity, narrow concentration range, non-Nernstian response, long response time and poor reproducibility [10][11][12][13][14][15][16][17][18][19][20]. Contrary to this, the dibenzocyclam macrocycles could prove to be a better candidate for development of Ni 2+ selective electrodes.…”

“…The γ-carbon atoms in MR 4 taa complexes possess remarkable nucleophilicity [21], which can be exploited for binding a variety of groups in order to build molecular super-structures and supramolecular assemblies [22]. The R 4 Bzo 2 [14]aneN 4 type dibenzocyclam derivatives due to their flat geometry are also expected to form stacks in solid lattices and are also expected to possess good miscibility with the PVC matrix for the rapid exchange of metal ions [23]. Consequently, they can be used as active material in the membrane phase to prepare selective electrode for a particular metal ion [24][25][26].…”
