The capture and long-term storage of volatile radionuclides, particularly iodine-129, remains a key challenge for nuclear waste management. Historically, zeolites (aluminosilicate chemistries) have been the primary material explored for this capture due to their controllable porosity, which allows for efficient iodine uptake but sacrifices mechanical stability. However, aluminophosphates, either amorphous or with zeolite-like structures, may offer a versatile approach for iodine containment. Aluminophosphates are valuable for their flexible chemistries, chemical durability, and thermal stability. Exploring aluminophosphate materials can provide improved stability and chemical durability with lower processing temperatures, leading to higher iodine retention. The work highlights the potential of aluminophosphate materials as long-term, durable iodine storage for nuclear energy applications. |
