“…Pazik and Skwierawska reported on 11 di-and triamide functionalized tetrazole derivatives as ionophores in ionselective membranes. 182 One compound showed considerable selectivity for ammonium over most other tested ions, including potassium (logK NH 4 ,K pot = −2.0). Other compounds were shown to exhibit some preference for either Cd(II) or Pb(II), but with more modest selectivities compared to the current state of the art.…”

This Review describes, with 200 references, progress with ion-selective electrodes, membrane electrodes, and ion transfer voltammetry in the period between January 2013 and September 2015. The selection of papers was done at the author’s discretion and should therefore be understood as an opinion piece and a current snapshot of the activity in the field. Contributions were sourced from modern search engines, primarily SciFinder, searching for relevant keywords and known author names. Some journal tables of contents were also screened manually. Please accept my apology if a reader feels that his or her important contribution has been left out. Perhaps I simply did not see it

Selective Recognition of Ammonium over Potassium Ion with Acyclic Receptor Molecules Bearing 3,4,5-Trialkylpyrazolyl Groups

Among the 1,3,5-trisubstituted 2,4,6-triethylbenzenes bearing pyrazolyl groups, the compounds with 3,5-dimethylpyrazolyl moieties were found to be effective receptors for ammonium ions (NH4+). The current study investigated the extent to which the incorporation of an additional alkyl group in the 4-position of the pyrazole ring affects the binding properties of the new compounds. 1H NMR spectroscopic titrations and investigations using isothermal titration calorimetry revealed that this small structural variation leads to a significant increase in the binding strength towards NH4+ and also improves the binding preference for NH4+ over K+. In addition to the studies in solution, crystalline complexes of the new triethyl- and trimethylbenzene derivatives, bearing 3,4,5-trialkylpyrazolyl groups, with NH4+PF6¯ were obtained and analyzed in detail. It is noteworthy that two of the crystal structures discussed in this work are characterized by the presence of two types of ammonium complexes. Studies focusing on the development of new artificial ammonium receptors are motivated, among other things, by the need for more selective ammonium sensors than those based on the natural ionophore nonactin.

“…As ion-selective sensors (ISSs) have found wide use for the direct determination of ionic species in complex samples [8–19] , it is a point of view in this study. In the early days, their selectivity was often the limiting factor in determining low levels of analyte ions.…”

New rapid, sensitive and simple electrometric method was developed to determine sertraline hydrochloride (Ser-Cl) in its pure raw material and pharmaceutical formulations. Membrane sensors based on heteropolyacids as ion associating material were prepared. Silicomolybdic acid (SMA), silicotungstic acid (STA) and phosphomolybdic acid (PMA) were used. The slope and limit of detection are 50.00, 60.00 and 53.24 mV/decade and 2.51, 5.62 and 4.85 μmol L−1 for Ser-ST, Ser-PM and Ser-SM membrane sensors, respectively. Linear range is 0.01–10.00 for the three sensors. These new sensors were used for the potentiometric titration of Ser-Cl using sodium tetraphenylborate as titrant. The surface morphologies of the prepared membranes with and without the modifier (ion-associate) were studied using scanning and atomic force microscopes.
