Process for eliminating metal ions from a metal ion-containing liquid with solid chelate resins

摘要

Metal ions, for example, heavy metal ions, alkaline earth metal ions and aluminium ions are eliminated by bringing a liquid containing the metal ions into contact with a special chelate resin in which chelating carboxylic anion groups are associated with basic amino acid cations, for example, lysine, ornithine, histidine, arginine, , - diaminopropionic acid, ,-diaminobutyric acid, L- citrulline and -oxylysine.
