News: A new study published in Environmental Science & Technology reports a breakthrough in removing tritium from contaminated water using a metal-organic framework (MOF).
About Tritium
- It is a radioactive isotope of hydrogen.
- Properties:
- Atomic mass: It has an atomic mass of 3.014 and is considered an important and versatile radioisotope.
- Components: It consists of one proton and two neutrons. It is unstable.
- Half-life: The physical half-life of tritium is 12.33 years, meaning that it takes just over 12 years for tritium to decay to half of its original amount.
- When it bonds with oxygen, it forms tritiated water, or HTO.
- It decays over time, and while decaying, it emits beta radiation. As tritium decays, it changes to helium.
- Production: It is produced naturally from interactions of cosmic rays with gases in the upper atmosphere, and is also a by-product of nuclear reactors.
- Uses: It is combined with phosphor to produce self-luminous lighting used in exit signs, emergency lighting, and airport runway markers.
- It is also used as a radioactive tracer in biomedical research to study and diagnose diseases such as heart disease, cancer and AIDS.
- In the future, it is expected to play a key role in generating electricity through nuclear fusion reactors.
About the Recent Findings
- A new study found a promising way to remove tritium more efficiently.
- Researchers from China developed a new material called a metal-organic framework (MOF), a highly porous material often described as a microscopic sponge.
- They coated a stainless-steel mesh with this MOF, called NH₂-MIL-101(Cr).
- The new material works in two ways:
- It provides a much larger surface area for separating water.
- It captures tritium atoms and replaces them with normal hydrogen atoms.
- Result: In laboratory tests, this method performed 134 times better than the best existing industrial material and about one million times better than standard commercial packing materials used in distillation towers.
- Applicability: The researchers believe this technology could make it much easier and cheaper to remove tritium from contaminated water, helping reduce radioactive releases into the environment and improving the safety of nuclear waste management.
