Abstract: Tritium is isolated and recovered from tritium-containing water by a membrane electrode including a manganese oxide having a spinel crystal structure and containing hydrogen ions or lithium ions and having one surface coated with a membrane of an ion conductive material.
Abstract: To provide an absorbing material to separate tritium from heavy water. By using a deuterium ion- or hydrogen ion-containing manganese oxide having a spinel-type crystal structure as a tritium absorbing material collecting tritium from heavy water containing tritium, tritium can be separated and recovered inexpensively from the heavy water.
