Adsorption of Indoor Carbon Dioxide on Potassium Carbonate Supported on Zeolite

초록

Carbon dioxide concentration of indoor spaces can be very high if there is not proper ventilation. High concentration of carbon dioxide is known to cause headache, sleepiness, languor, and lower concentration. Though ventilation is one of the easiest ways to control carbon dioxide concentration, it is not applicable when the outdoor air is polluted by various pollutants. In this study, carbon dioxide adsorbent using potassium carbonate was prepared, and its adsorption performance was extensively investigated. The repetitive use performance of this adsorbent was also studied by repeating adsorption-desorption cycle.
