ABSTRACT:
This invention relates to a process for separating heavy water from solutions. An anionic surfactant system is added to a solution of deuterium oxide in water. The separating agent added to the solution will form a first phase containing a majority of the surfactant with an increased concentration of D.sub.2 O and a second phase containing excess water with a decreased concentration of D.sub.2 O. The first stage is separated from the second stage, and the process is optionally repeated in a multi-stage or a continuous operation.
