Process for removing heavy-metal ions from aqueous solutions |
摘要 |
A process for removing heavy-metal ions from aqueous solutions, particularly from effluents. The process comprises bringing the aqueous solutions into contact with a water-insoluble adsorbent which has been produced from: (a) a basic polynitrogen compound capable of being acylated; (2) an aliphatic or araliphatic carboxylic acid containing mobile substituents or a multiple bond capable of undergoing addition; and (3) a crosslinking compound which contains at least two reactive substituents and which is different from component (2).
