Capture of iodine in a radiation stable metal organic framework (MOF)

Entrapment of I₂ in a radiation stable metal organic framework has been investigated gravimetrically both under dry and 33% RH. The release of trapped I₂ has also been investigated by TG-coupled with EGA. The results indicate that the framework can absorb ~60 and ~64 wt% I₂ under dry and 33% RH condition respectively. The framework does not show any loss of crystallinity even at 1.75 MGy gamma radiation dose. During the last decade the world has seen a significant escalation in energy demand. Nuclear being an emission free high density green energy source plays a vital role in the fulfilment of such demand. The success of Indian Nuclear Power program depends to a great extent on the successful management of radioactive waste. The involvement of I₂ in human metabolic process forced us to trap the radioactive I2 before it gets release into the environment. In the present article the feasibility of a radiation stable MOF for I₂ entrapment is discussed
