We describe a method for determining mass-exchange and capacitance characteristics of chemisorbents of carbon dioxide. Through a cartridge equipped with a chemosorbent, a gas-air mixture is blown continuously from a sealed container of a small volume into which the impurity of carbon dioxide is continuously introduced. The gas-air mixture, which has been purified from the impurity, is again introduced into the tank. The concentration of carbon dioxide in a sealed volume is monitored by means of the gas analyzer; the effective mass transfer coefficient and the maximum capacity of the chemisorbent for carbon dioxide are calculated from the obtained data.
