Extraction et purification par nanofiltration et osmose inverse de métaux. Etude de la sélectivité

Abstract

The present pilot scale study consists of the optimization of the ion separation process of (III), Fe (III), Ni (II), Co (II), Cu (II), Zn (II) ), Cd (II), & Pb (II) from an industrial waste solution and the La (III) / Fe (III) and Cu (II) / Fe (III) ions from their synthetic mixture, by the nanofiltration technique and reverse osmosis, several experimental parameters have been studied such as: effect of the initial concentration, pressure effect, pH effect. The performance of lanthanum extraction by nanofiltration is studied using the methodology of experimental designs 3
