Cationic adsorption agent

A cationic adsorption agent which is obtained by reaction of (a) an amino compound which contains at least one amino group and at least one free or methylolated carbamide or thiocarbamide group, or a salt thereof, with (b) an aminoplast precondensate which does not contain amino groups. The novel ab...

Beschreibung
Zusammenfassung:	A cationic adsorption agent which is obtained by reaction of (a) an amino compound which contains at least one amino group and at least one free or methylolated carbamide or thiocarbamide group, or a salt thereof, with (b) an aminoplast precondensate which does not contain amino groups. The novel absorption agent is suitable in particular for removing anionic substances, such as acid dyes or reactive dyes, from aqueous solutions, especially from wastewaters.
