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, alpha , beta -diaminopropionic acid, alpha , gamma -diaminobutyric acid, L-citrulline and delta -oxylysine. |
