“…In order to find selectivity behavior of H 2 Me 2 bpb toward cations, its interaction with lanthanide ions and other common mono, di and tri valent ions were investigated conductometrically in an acetonitrile solution by previously describe method [32][33][34][35]. The complex formation constant, K f , shows the selectivity of the used ionophore toward Ho 3+ ions (K f : 5.6×10 6 ) among the all other cations tested.…”

“…A Pyrex tube (3-5 mm o.d. on top) was dipped into the mixture for about 5 s, so that the formation of a transparent membrane (about 0.3 mm thickness) could be achieved (Behmadi et al 2007;Pooyamanesh et al 2007;Shokrollahi et al 2007;Ganjali, Moghaddam et al 2006;Zamani, Abedini-Torghabeh, and Ganjali 2006;Zamani, Rajabzadeh, and Ganjali 2006b;Abedi et al 2007;Zamani, Ganjali, and Adib 2007b;Saleh, Soliman et al 2006;Ganjali, Dodangeh et al 2006;Ganjali et al 2007;Zamani, Ganjali, Norouzi, Meghdadi 2008b;Norouzi, Adib, Rezapour, and Accedy 2005;. Then, the tube was removed from the mixture, kept at room temperature for 12 h, and filled with an internal solution (1.0 Â 10 À3 M SrCl 2 ).…”

This work introduces a unique ionophore for the selective determination of Sr 2þ ions. The ionophore, salicylaldehyde thiosemicarbazone (ST), presented a high affinity toward the strontium cations. The demonstrated characteristics of the sensor included a linear dynamic range between 1.0 Â 10 À6 and 1.0 Â 10 À2 M with a near Nernstian slope of 29.4 AE 0.5 mV per decade, a detection limit of 4.8 Â 10 À7 M, and a very good selectivity for Sr 2þ over other cations in a wide pH range (2.8-10.4). The sensor possessed the advantages of short conditioning time, fast response time (<10 s), and, especially, good selectivity toward the transition and heavy metal ions as well as some mono, di, and trivalent cations. Concerning the electrode lifetime, no considerable potential divergence was noticed for at least 10 weeks. The developed sensor was successfully used as an indicator electrode in the Sr 2þ titration with EDTA from binary mixtures, and the Sr 2þ monitoring in mixtures of three and five different ions.

A highly selective and sensitive poly(vinyl chloride) membrane electrode, using 4-4 0 -Methylenediantipyrine as an ionophore, has been prepared and examined as a Ba 2þ -selective electrode. The influence of the anion excluder (sodium tetraphenyl borate, NaTPB) and the effect of the plasticizers dibutyl phthalate (DBP), nitrobenzene (NB), and benzyl acetate (BA) were studied. The best performance was obtained with the sensor having a membrane composition (w=w) of (MAP, 2.0%), (PVC, 30%), (NB, 66%), (NaTPB, 2.0%) with a wide working concentration range of 1.0 Â 10 À6 to 1.0 Â 10 À2 M between the pH values of 3.4 and 10.6. Furthermore, a Nernstian slope of 29.7 AE 0.3 mV= decade of activity was demonstrated with a response time of 15 s. The sensor could be used over a period of 2 months with no potential divergence, revealing a good selectivity for a broad variety of cations including alkali, alkaline earth, heavy and transition metals. Regarding the practical applicability of this sensing device, it was successfully applied for the Ba 2þ ions detection in a lithophone pigment and as an indicator electrode in the potentiometric titration of the under study cations.
