Static iodine loading comparisons between activated carbon, zeolite, alumina, aerogel, and xerogel sorbents

Abstract

Different sorbents, including activated carbons, an Ag-aerogel, Ag-xerogels, an Ag-alumina, an Ag-zeolite, a Ag₂S-polyacrylonitrile composite, and a carbon foam were investigated for static I_2(g) loading at 71 °C for 56 d followed by 4.7 d of desorption. The iodine loadings were 630–1249 mg g⁻¹ for activated carbons and 87–744 mg g⁻¹ for other sorbents.
