Ammonia Gas Absorbency

Ammonia is one of the major causes of unpleasant household odours, for example from pets and bathrooms.


Each column (25 mmØ x 115 mmL) was filled with 60 ml of sample. Ammonia gas (at a density of 500 ppm) was blown in at 500 ml per minute. The density of the gas at each outflow (the leakage density) was measured and the absorption rate was calculated. SumiBall was found to continue absorbing 100% of the ammonia gas for more than 20 hours!
