Abstract
Both sulfonic acid and carboxyl groups were introduced onto the pulp ball by radiation-induced graft polymerization. The resultant grafted material sorbed ammonia gas due to neutralization. Concentration decay of ammonia gas was determined in a closed vessel, and apparent sorption capacity of gas was calculated as integration of repeated deodration. Superioriy of the grafted deodorant was demonstrated in comparison with three commercial products and an activated carbon.
