In this study, the ammonia gas adsorptivity was evaluated by carbide of coffee beans residue. Ammonia gas was used as a test gas. When organic compounds included some nitrogen atoms are rotted, ammonia gas breaks out. It has irritating smell. And, it shows corrosion effect for metal plating, copper and aluminum. 10 to 1000ppm ammonia gas concentrations were prepared in globe bags with the carbide samples. After 15min, 1h and 24h gas concentration in each glove bags were measured by gas detector tubes. The carbide samples of the coffee bean residue showed excellent ammonia gas adsorptivity.
