    Description / Table of Contents: Zusammenfassung Die Abtrennung gelöster Spurenelemente an einem Celluloseaustauscher mit 1-(2-Hydroxyphenylazo)-2-naphthol als chelatbildende Ankergruppe wird beschrieben. In Schüttelversuchen werden Schwermetallionen aus 100 ml Lösung auch in Gegenwart von 0,5 M NaCl angereichert. Sie können anschließend direkt durch Röntgenfluorescenzanalyse bestimmt werden. In Trennsäulen werden die Elemente Fe, Cu, Zn, Pb und U aus Trinkwasser nahezu quantitativ abgetrennt.
    Notes: Abstract The separation of trace elements dissolved in water on a cellulose exchanger containing 1-(2-hydroxyphenylazo)-2-naphthol as chelating group is described. In batch experiments heavy metal ions are enriched from 100 ml solution, even in presence of 0.5 M NaCl. They can be determined afterwards directly by X-ray fluorescence. In separation columns the elements Fe, Cu, Zn, Pb and U are separated from drinking water nearly quantitatively.
