    摘要: A polysaccharide-containing adsorbent for the removal of heavy metal ions from an effluent which adsorbent has been manufactured from(1) a polysaccharide-containing material,(2) a basic, nitrogen-containing polymer which can be acylated,(3) a crosslinking compound, which is different from component (4), containing at least two reactive substituents and, optionally,(4) an aliphatic or araliphatic carboxylic acid containing a mobile substituent or a multiple bond which is capable of undergoing addition.

    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).
