Relation between concentration change of some metal salts in aqeous solution and their membrane potential was measured by the new types of membrane-electrode with ion-exchage membranes, "Selemion" series, prepared by Asahi-Glass-Co. From this data, CSG and CMV cation-exchange-membranes were selected as most suitable species for analysing of metal ions in solution. This membrane-electrode-method was applied to some other investigations as follow, and confirmed excellent analytical equipment, such as electrical-conductivity method and usual potential-method. 1) Determination of the mobitities of some bi-valent-metal ions in the membranes. 2) Application to the endpoint detecter of acid-base titration and precipitation titration. 3) Measurement of ionic concentration in organic solvent systems.
