摘要:
A fibrous material useful for treating a waste water having a suitable amount and ratio of hydrophobic group and hydrophilic group is produced by reacting a fibrous material with sulfuric acid and/or chlorosulfonic acid, and then with alkylamines having 2 to 20 carbon atoms and optionally finally with, for example, ammonia, amines and/or hydrazines.
