Grases, F. published the artcileReactions between technetium(VII) and some hydrazones and the spectrofluorometric determination of technetium(VII) with 2,2′-dipyridyl ketone hydrazone, Product Details of C11H10N4, the publication is Analytica Chimica Acta (1984), 71-8, database is CAplus.
The reactions between pertechnetate and 5 hydrazones are described. Of these, the Tc(VII)/2,2′-dipyridyl ketone hydrazone system was found to be most sensitive, and was studied in detail. Spectrofluorometric procedures for the determination of Tc(VII) over the range 0.01-12 mg L-1 are reported. The reaction proceeds most favorably under acidic conditions (1.4M HCl). For 1 mg L-1 Tc(VII), 100 mg L-1 levels of U(VI), Re(VII), Mo(VI), or W(VI) do not interfere when the reaction proceeds at room temperature Sensitivity improves at higher temperatures
