Cationic adsorption agent

摘要

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 carboxamide group, with (b) an aminoplast precondensate which does not contain amino groups. The novel adsorption agent is suitable in particular for removing anionic substances, such as acid dyes or reactive dyes, from aqueous solutions, especially from wastewaters.
