## Abstract For certain ionophores of extremely high lipophilicity, kinetic limitations of the carrierβinduced ion transfer between aqueous and membrane phase may heavily disturb the electromotive behaviour of the ionβselective membrane electrode. These limitations may be overcome by adding tetraph

β¦ Synopsis
Neutral-carrier-based ion-selective electrodes for the assay of alkali and alkaline earth metal cations have advanced to become the most frequently used potentiometric sensors in clinical chemistry . The major developments since the realization of the first potentiometric cell assemblies utilizing electrically neutral complexing agents (valinomycin and the macrotetrolides) in 1966 are presented .

They unambiguously confirm that such bulk membranes dispose of immobile anionic sites. These fixed sites lead to a D
Hydrogen ion selective solid contact electrode based on tribenzylamine have shown the best Nernstian slope, selectivity and the widest response range in Tris buffered pH sample solutions. Their linear dynamic range was pH 2.48-11.21 and Nernstian slope showed 55.1 mV=pH (at 20 AE 0.2 C). When it was
A PVC membrane electrode for aluminum(III) ions based on Furil (ethan dione, di-(2-furyl)) as neutral carrier was prepared. The electrode exhibits a near Nernstian response for Al 3ΓΎ ions over a wide concentration range (1.0610 76 to 1.0610 72 mol dm 73 ) with a limit of detection 1.3610 77 mol dm 7
