Abstract
The composite sorption material based on a highly porous polyurethane foam matrix with a layer of impregnated activated carbon powder applied to its surface has been developed. The reticulated polyurethane foam Regicell was used as a base for the sorbent samples. The compounds that most effectively inhibit the combustion process were: phosphates, sulfates, borates and pyrosulfates. The selection of the optimal amount of the fire retardant was carried out, and the sorption capacity of the material samples in relation to radioactive methyl iodide was studied. It became clear that the sorbent treated with a 20 % solution of ammonium sulfate can be classified as a material with low combustibility. The study of the sorption capacity was carried out on a certified stand under conditions corresponding to the standard test method for nuclear power plants iodine sorbents. During the tests, more than 99.9 % radioactive methyl iodide trapping efficiency was achieved, which exceeds that for the industrial granular sorbent selected as a comparison. It was found that the gas flow hydraulic resistance corresponding to the manufactured samples is lower than that of the industrial one. The relative sorption capacity index was used as a criterion for comparing the sorption capacity of materials characterized by different free volume fractions.
