Abstract: A procedure is developed for the Spectrofluorimetric determination of 10–800 ppb of zinc with pyrocatechol-1-aldehyde salicyloylhydrazone in a 60% (v/v) ethanol-water medium at apparent pH 6.7 (acetic-acetate buffer). λex=400 nm, λem=530 nm. Interferences have been evaluated and the method applied to the determination of zinc in alloys and lubricating oils.
Zink bildet mit Brenzcatechin-1-aldehyd-salizyloylhydrazon ein gelbes, fluoreszierendes Chelat in Gegenwart von 60% Ethanol bei pH 6,7 (Essigsäure-Natriumacetat-Puffer); λex=400 nm, λem=530 nm. Zwischen Intensität der Fluoreszenz und Zink-Konzentration besteht im Bereich von 10 bis 800 ppb Linearität. Das Verfahren wurde zur Bestimmung des Zinks in Legierungen und Schmierölen verwendet.
