ABSTRACT:
The invention is related to a method and an installation for removal of metal cations contained in a liquid, in which said liquid is brought into contact at a temperature greater than or equal to 60° C. with a chelating ion exchange resin formed from a polyazacycloalkane grafted on a solid support, said resin having been conditioned, previously to said contacting, at a pH of 4 to 6.
