| الوصف: | Sulfur dioxide sorption by artificial and synthetic fibers as well as needlepunched nonwoven fibrous materials (IVHS-PEPA) impregnated with polyethylene polyamine (PEPA) under static and dynamic conditions has been investigated. It was found that when the vapor H2O and SO2 were present together the adsorption on the surface of the initial fiber had the competitive character, wherein the polar water molecules through hydrogen bonds to block the active sites of the fibers resulting in reduced absorption of sulfur dioxide in comparison with dry samples, throughout the range of values of the relative water vapor pressure (р/рs = 0÷0,92). It was found that the process of chemisorption of SO2 IVHS-PEPA occurs only in the presence of «free» water. It is shown that the import-substituting IVHS-PEPA based lavsan fibers are not inferior to the protective characteristics of the best foreign fibrous chemisorbents brand VION. |
