Abstract
A novel process for the purification of industrial effluents, wherein the effluents are brought into contact with cationically modified, cellulose-containing materials, the cationic constituent of which is bonded to the cellulose part via the grouping of the general formula EQU --O--CH.sub.2 --N< in which the nitrogen belongs to an amide group of the cationic constituent and the oxygen is bonded to the cellulose part, and the cationically modified, cellulose-containing materials possessing such a constituent, are disclosed.
