Fluoreszenzanalytische bestimmung von sulfidionen im nanogrammbereich

Zusammenfassung Zur Bestimmung von Sulfid im Bereich von 1–10 ng ml wurde eine Methode ausgearbeitet, die auf der Fluoreszenzloschung einer alkalischen Losung von Fluorescein-mercuri-acetat (FMA) durch Sulfid oder andere Schwefelverbindungen beruht. Zur Standardisierung wird eine Diphenylthioharnstofflosung verwendet. Die Standardabweichung fur die Bestimmung von 3,5 ng ml Sulfid war 0,17 ng ml . Die Methode eignet sich zur Bestimmung kleinster Schwefelmengen in organischen Substanzen nach einem hydrierenden Aufschlus.
