Removal of gaseous fission products by adsorption

An Economical Modification Method for MIL-101 to Capture Radioiodine Gaseous: Adsorption Properties and Enhancement Mechanism

“…Radioactive iodine usually exists in the form of iodine, which is easily diffused. It will enter the human body through various media such as air, water, and food, and then it is rapidly enriched by the human thyroid gland, thereby causing various thyroid diseases [2]. Currently, there are 37 known types of iodine isotope and their mass numbers are ranging from 108 to 144.15 types of radioiodine are produced by nuclear power plant.…”

Sorption Properties of Activated Carbons for the Capture of Methyl Iodide in the Context of Nuclear Industry

“…In humid conditions, CH3 I adsorption is considered to be driven by a proto nation mechanism according to recent Density Functional Theory (DFT) calculations [12]. However, the KI impregnation seems to be responsible for an isotopic exchange reaction between the radioac tive gaseous iodine species and the stable iodine on the adsorbent phase [8,13,14].…”

Measurement of I-129 in environmental samples by ICP-CRI-QMS: possibilities and limitations

“…activated carbon, zeolite, silica gel or alumina), etc., have been evaluated for removing radioactive iodine from the effluent or off-gas of the nuclear fuel reprocessing plant. Despite the problems related to the cost and the possible leaching of silver under acidic condition, silver impregnated materials show generally more efficient sequestration of iodine comparing with other materials [27][28][29][30][31][32]. Taking into account the efficiencies reported in the literature and the stability of AgI, which is the dominant product from the sequestration of iodine when excess amount of silver exist [29], silver impregnated materials may be a solution for the tasks in which preconcentration of iodine from large amount of natural water is critical for analysis of 129 I. Iodine fixed as AgI can be released into solution through reaction Eq.…”
