PROCESS FOR PRODUCING CHELATISING ION-EXCHANGE RESINS AND THEIR USE IN METAL EXTRACTION

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.
