Zum Mechanismus der Trennung von Anionen an mit vernetzter Poly-(dibenzo-18-krone-6) beschichtetem Kieselgel

Silica gel Si 100 coated with cross-linked poly(dibenzo-18-crown-6) is suitable for ion chromatography. Chromatographic separations of numerous anions can be accomplished with only water as eluent. Two effects overlap, ion exclusion, and complex forming of salts with the crown ether.
