Novel solid-contact iodide-selective electrodes based on covalently attached 1,2,3 triazole ionic liquid (IL) were prepared and investigated in this study. Triazole-based IL moieties were synthesized using click chemistry and were further copolymerized with lauryl methacrylate via a simple one-step free radical polymerization to produce a "self-plasticized" copolymer. The mechanical properties ...

Porous surface modified polyvinylidene ï‌‚uoride (PVDF) hollow fiber membranes are fabricated through a dry-wet phased inversion process. Surface modifying macromolecules (SMM) (1 wt. %) are used as additives in the spinning dope. The performance of the surface modified membrane in contactor application for CO2 stripping from water is assessed through the fabricated gas–liquid membrane contacto...

The "apparent" cation transference number within cellophane is determined for HCl, KCl, NH(4)Cl, NaCl, and LiCl. The method consists in measuring the E.M.F. in a concentration chain employing Ag:AgCl electrodes or calomel electrodes and calculating from formulas derived for cases of simple, unconstrained diffusion. The transference numbers and the cation mobilities relative to the chloride ion ...

Various types of errors during the measurements of ion-selective electrodes, ionsensitive field effect transistors, and fibre optic chemical sensors are described. The errors were divided according to their nature and place of origin into chemical, instrumental and non-chemical. The influence of interfering ions, leakage of the membrane components, liquid junction potential as well as sensor wi...

Recently, a disruptive idea was reported about the discovery of new type battery named Liquid Displacement Battery (LDB) comprising liquid metal electrodes and molten salt electrolyte. This cell featured novel concept porous electronically conductive faradaic membrane instead traditional ion-selective ceramic membrane. LDBs are attractive for stationary storage applications but need mitigation ...

Ion-selective electrodes (ISEs) are widely used in clinical examinations. The mechanisms of ISEs have been studied to develop a disposable ISE for "dry chemistry" analyses. The behavior of Na+ and Ag+ in an ion-selective polymer liquid membrane (ISM) containing methyl monensin (MMO), which is selective for Na+, has been clarified by x-ray microanalysis and measurement of electrical potential. T...
