Process for preparing chelating ion exchanger resins and the use thereof for the extraction of metals

摘要

The invention relates to a process for preparing complex- forming ion exchanger resins which contain 8-hydroxyquinoline groups and can be prepared from carrier materials containing amino groups reactive with aldehydes, and aldehydes, 8-hydroxyquinoline and/or 8- hydroxyquinoline derivatives, and to the use thereof for the selective extraction of metals from aqueous solutions.
