    Description / Table of Contents: Zusammenfassung Auf DC-Plastikfolien getrennte Substanzen lassen sich mit guter Genauigkeit (Wiederfindungsraten 〉 95 %) in Gegenwart des Folienmaterials gleichspannungspolarographisch durch Reduktion an der Hg-Tropfelektrode bestimmen. Die von den Leuchtpigmenten abgegebenen Zn-Ionen müssen vor der Registrierung der i-E-Kurven durch ÄDTA maskiert werden.
    Notes: Abstract Organic compounds with polarographically active groups can be determined after separation by thin-layer chromatography on flexible polyester film by means of dc polarography in the presence of the foil. Heavy metal cations, such as Zn2+, derived from the fluorescent material of the stationary phase must be masked by complex formation with EDTA before the current-voltage curve is recorded. Recovery is 〉 95%.
