Abstract

This study reports the separation of tritium from tritiated heavy water at room temperature using a membrane containing deuterated manganese dioxide. A continuous decrease in the tritium concentration in tritiated heavy water was observed when using the membrane. Furthermore, the dissolution of manganese ions from the membrane into tritiated heavy water was remarkably decreased by adding an adequate amount of lithium chloride to the tritiated heavy water.
