title: Zur Frage des Verlustes von Molybdän während der Analyse von metallischem Wolfram auf Molybdänspuren.
abstract: It is shown that oxidative ignition of metallic tungsten to tungsten trioxide causes a decrease in the molybdenum content. Thus the ignition cannot be used when the molybdenum content is to be determined. On the other hand, when the tungsten is dissolved in a mixture of hydrofluoric and nitric acids with subsequent fuming with sulphuric acid, no such decrease in the molybdenum content takes place.
