| 摘要 |
<p>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-form-ing 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.</p> |
