| Abstract: | Summary A procedure is described for the determination of 0.2–3.5 mg of the diphenyliodonium cation by extraction of its hexathiocyanatoferrate(III) Complex from slightly acidic solution into 1,2-dichloroethane. Absorbance measurements are made directly on the organic extract at 485 nm. Beer's law is not obeyed and a calibration curve must be used.
Zusammenfassung Ein Verfahren für die Bestimmung von 0,2 bis 3,5 mg Diphenyljodoniumkation durch Extraktion seines Hexathiocyanatoferrat(III)-komplexes aus sehwach saurer Lösung mit 1,2-Dichloräthan wurde beschrieben. Die Absorption des organischen Extraktes wurde unmittelbar bei 485 nm gemessen. Das Beersche Gesetz ist nicht anwendbar, weshalb man eine Eichkurve verwenden muß.
