摘要： A uranyl ion selective electrode having a responsive membrane, an inner reference electrode, and a uranyl ion inner solution is disclosed, in which the responsive membrane is obtained by treating a membrane material with an ion-exchanger comprising at least one uranyl ion complex formed between a uranyl ion and a neutral phosphoric ester or a neutral phosphorous ester as a complexing agent, a diluent excellent in compatibility with the ion-exchanger, and a solvent mediator having affinity for the membrane material. The electrode is excellent in concentration responsiveness, reproducibility, accuracy, and durability and is particularly suitable for use in uranyl ion analysis in the atomic energy industry.
