Electrochemical Behavior of Cation Exchange Membranes^1,2 in Liquid Ammonia

Potentiometric in Situ Monitoring of Anions in the Synthesis of Copper and Silver Nanoparticles Using the Polyol Process

“…Anion-exchange resins were first developed in the 1930s for ion-exchange separations, and they have been used in organic solutions with relatively high dielectric constants . ISEs with resin-based, ion-exchange membranes were used to measure ion concentrations in aqueous samples as early as the 1950s , and also found applications for measurements in liquid ammonia and ethanol . More recently, Bakker and co-workers showed that commercially available hydrophilic ion-exchange membranes can be used to prepare potentiometric ion sensors for the measurement of chloride in blood …”
