From electrochemical measurements at the interface of two immiscible electrolytes, the current at controlled potential is usually a linear function of the ion concentration in the aqueous phase. Surprisingly, a linear relationship between the current

Potentiometric selectivities and lower detection limits of ion-selective electrodes have been dramatically improved through better design of the electrodes. Ion-selective electrodes may now compete with the most sophisticated techniques of ultratrace
