Removal of metal ions from aqueous solutions by micellar enhanced ultra-filtration (MEUF)


The results of preliminary research on the possibility of removing of chromium(III) and copper(II) ions from micellar solutions in MEUF were described. The effectiveness of metal ions removal in the classical UF and MEUF was compared. It was confirmed that in the classical UF the retention of metal ions is small, independent of the concentration of the feed solution. The cross-flow micellar enhanced ultrafiltration experiments showed the usefulness of this method for the separation of metal ions from micellar solutions. The retention of metal ions in MEUF process is almost total in the case of the solutions of low concentration. However, for more concentrated solutions the retention is much smaller.
