摘要：

The facilitated transport of CO2 through a cation-exchange membrane has been studied. The carrier, monoprotonated ethylenediamine, is introduced in the membrane by soaking acidic samples in more or less concentrated neutral ethylenediamine solutions. The permeability of the membrane is determined as a function of the CO2 mole fraction in the uphill binary (CO2/N-2) gas mixture. The experimental results have been interpreted using a transport model based on the Nernst-Planck equation. The use of a highly swollen membrane enhances the ionic mobilities and leads to high selectivity and permeability.
