Sorption of CH_3 ~(131)I from the Water Vapor-Air Medium onto Nanocomposite Materials

摘要

Sorption of CH_3~(131)I from the water vapor-air medium onto inorganic nanocomposite materials containing 1, 2, 4, and 8 wt % Ag in various chemical forms was studied. Despite high ability of the synthesized nanocomposite materials containing 1, 2, and 4 wt % Ag in various chemical forms to take up ~(131)I_2 (>99%), they cannot be used for localizing CH_3~(131)I from the gas flow. The material containing 8 wt % Ag, namely, the SiO_2-8% Ag nanocomposite prepared by treatment of the precursor with a 0.01 M hydroxylamine solution, is the most suitable for this purpose.
