Notes:
For certain ionophores of extremely high lipophilicity, kinetic limitations of the carrier-induced ion transfer between aqueous and membrane phase may heavily disturb the electromotive behaviour of the ion-selective membrane electrode. These limitations may be overcome by adding tetraphenylborates to the membrane phase. Membranes prepared with different 3,6-dioxaoctanediamide homologues and potassium tetrakis(P-chlorophenyl)borate as phase-transfer catalyst all exhibit the same ion selectivity as well as theoretical electrode response. This behaviour is corroborated by a theoretical description of the ion-transfer process.
