イオン交換膜電極法とその応用 : 第一報 市販イオン交換膜を使用した膜電極の製作とその電位特性について

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
