title: [The study on CO2 concentration in solid amine CO2 control system].
abstract: OBJECTIVE
  To solve the problem of CO2 concentration and collection in solid amine CO2 control system for long-duration spacecraft cabin.
  
  
  METHODS
  One approach was presented on the base of the principle of absorption and desorption, and was then tested by the apparatus according to it.
  
  
  RESULTS
  The average concentration of the concentrated CO2 was as high as 95%, which can be directly sent to the CO2 reduction system, and about 90% of the concentrated CO2 can be collected.
  
  
  CONCLUSIONS
  The designed apparatus met the requirements of the CO2 reduction system.
