Abstract
A dextrane-polyacrylic acid mixture was found to be a good phase-separ ating agent for aqueous solutions and to be applicable to the solvent extraction of tris(1,10-phenanthroline)iron(II)([Fe(phen)3]2+). Iron(I I) was extracted as an ion-pair with polyacrylic acid. Such extraction conditions as the mixing ratio of two polymers, the pH, and the tempe rature during centrifuging were examined.
