Weakly basic anion exchange resins, process for their preparation by aminolysis and use for removing sulfates ions from acqueous solutions |
| abstract |
Weakly basic anion exchangers of the poly(meth)acrylamide type, which have been prepared by aminolysis of poly(meth)acrylonitrile or poly(meth)acrylate with polyamines of a defined composition, have an improved uptake capacity for sulphate ions and are suitable for selective removal of sulphate ions from aqueous liquids, especially from sodium chloride brines and from waste waters. |
