Removing metal ions with a membrane based on anionic polyarylene ethersulfone and a cationic polymer with amino groups

Abstract

The present invention relates to a method for removing metal ions from an aqueous system comprising a step of filtering the aqueous system through a loaded membrane which contains a carrier membrane based on a polyarylene ethersulfone which carries anionic groups, and a cationic polymer which is a polymer comprising primary and/or secondary amino groups. The invention further relates to a loaded membrane which contains a carrier membrane based on a polyarylene ethersulfone which carries anionic groups, and a cationic polymer which is a polymer comprising primary and/or secondary amino groups.
