摘要：

The adsorption of water vapour by chemisorptive fibre VION KH-1 with such counter-ions as H+, Li+, Na+, K+, Rb+, Cs+, Be2+, Ca2+, Sr2+, Zn2+, Cd2+, Hg2+, Ni2+, Co2+, Cu2+, Ag+, Al3+ and Fe3+ was investigated. It is shown that the adsorption isotherms of all studied samples are S-shaped and belong to group II according to the BET classification. To describe the obtained isotherms we proposed to use the modified three-parameter equation of the BET type considering sorbents fractality which is true in the range 0.05 much less than x much less than 0.95. The influence of counter-ion charge value and its radius on adsorption and thermodynamic parameters of the process was found out. (C) 1999 Elsevier Science B.V. All rights reserved.
