​Novel graphene membrane separates tritium from wastewater 

Researchers from Pohang University of Science and Technology (POSTECH) and the Korea Atomic Energy Research Institute recently developed a graphene-based technology that can separate dangerous tritium from radioactive wastewater in a liquid state.

Tritium is a radioactive hydrogen produced in nuclear power plants and mostly exists in the form of water molecules. When it enters the human body, it can emit radiation internally, making thorough management necessary; however, until now, tritium could only be separated in a gaseous state, and the removal of liquid-phase tritium remained a significant challenge.
