anionisches adsorbents, process of its manufacture and its use for the removal of cationic substances and schwermetallionen from waessrigen solutions.

摘要

An anionic adsorbent which has been prepared by reacting (a) a monomeric compound which contains at least one anionic group and at least one amide group, especially a carboxamide group, which can be methylolated, with (b) an aminoplast precondensate which is free from salt-forming anionic groups. The novel adsorbent is particularly suitable for removing cationic substances, such as cationic dyes, and a heavy metal ions from aqueous solutions, especially from effluents.
