GEL-FILTRATION OF SOLUBLE COLORED METAL HEXACYANOFERRATE(II) COMPOUNDS

The paper investigates the chromatographic behavior of copper and uanyl hexacyanoferrate(II) complexes in thin layer size-exclusion chromatography using a variety of polydextran stationary phases, including Sephadex G-75, G-150 and G-200 gel. It is shows that the investigated hexacyanoferrate(II) complexes are excluded from any Sephadex gel when eluted with distilled water but are adsorbed or precipitate when eluted with electrolyte solutions.
