Nuclear power as an alternative to fossil fuels becomes important to meet growing demand for energy owing to their high energy density and less emission of greenhouse gases. However, the release of the radiotoxic radionuclides such as 129I, 131I, 137Cs and 90Sr during the operation of power plants or more seriously during unexpected nuclear accidents could be significantly harmful to human and environment. Recently, therefore, the development of sorbent materials with strong affinity to I2 has attracted substantial research interest. Metal-organic frameworks (MOFs) have recently emerged as enabling materials for radioactive I2 sorption owing to their high surface area and designable and tailorable pore properties. In this work, we aim to discover the influence of metal ions and functional groups on the I2 capture. Several MOFs featured by their isostructures with various organic functional groups and metal ions were chosen as the model materials. The sorption kinetics of the MOF samples were investigated by the use of I2 dissolved in cyclohexane and I2 vapor. The properties of I2@MOF samples were thoroughly analyzed through UV-vis spectroscopy, single/powder x-ray diffraction (SXRD/PXRD) analyses, and thermogravimetric analyses (TGA).
