METHOD AND INSTALLATION FOR ELIMINATING METAL CATIONS FROM A LIQUID WITH POLYAZACYCLOALKANE RESINS GRAFTED ON A SUPPORT

摘要

The invention concerns a method and an installation for eliminating metal cations contained in a liquid, which consists in contacting said liquid, at a temperature not less than 60 DEG C, with a chelating ion-exchanging resin consisting of a polyazacycloalkane grafted on a solid support, said resin having been previously conditioned to be contacted at a pH of 4 to 6.
