Title: Selective strontium removal from a sodium nitrate aqueous medium by nanofiltration-complexation

Abstract

In aqueous medium, selective complexation increases the ionic separation by nanofiltration. The combination of nanofiltration and complexation can be applied to the nuclear effluents treatment. To separate radioelements from a sodium salt medium, poly(acrylic acid) is associated to the FILMTEC NF 70 membrane. Effects of transmembrane pressure, pH, ligand concentration and ionic strength on salts retention are described, and the complexation constants are estimated. Finally, to reach the objectives, a strontium two-stages concentration by nanofiltration-complexation with a control of retentate salinity is investigated in a nonactive solution case.
