Prelims

1. What is the primary challenge in separating tritiated water (HTO) from regular water?

   1. A Tritium has a boiling point identical to that of heavy water.
   2. B Tritium is chemically almost identical to regular hydrogen.
   3. C Tritium is not radioactive and does not react with oxygen.
   4. D Tritium is significantly heavier than hydrogen atoms.

2. What is the function of the metal-organic framework (MOF) NH2-MIL-101(Cr) in the context of the recent study?

   1. A It converts tritiated water into oxygen and hydrogen gas through electrolysis.
   2. B It serves as a passive filter to trap heavy metals in wastewater.
   3. C It acts as an active packing material to facilitate the swapping of tritium atoms with hydrogen atoms.
   4. D It acts as a catalyst to neutralize the radioactivity of tritium.
