ABSTRACT:
The invention relates to the use of macroporous weakly-basic anion exchangers, charged with palladium or platinum and based on crosslinked polystyrene, as catalysts for the removal of oxygen from aqueous media by catalytic reduction, a process for the preparation of these catalyst resins, and new macroporous weakly-basic anion exchangers, charged with palladium or platinum and based on crosslinked polystyrene, in which the amino groups are primary or secondary amino groups.
