    Description / Table of Contents: Summary In the turbidimetric determination of traces of phosphoric acid, in accord with the Hegedüs and Dvorszky version, employing strychnine nitrate, excellent reproducibility is attained only when the MoO3 employed for the preparation of the reagent contains 0.2–0.5% WO3/MoO3. If less than 0.01% WO3/MoO3 is present, large deviations in the obtained values ensue.
    Notes: Zusammenfassung Mit der turbidimetrischen Strychninnitrat-Methode für Phosphorspurenbestimmung nach der Version von Hegedüs und Dvorszky kann man nur dann ausgezeichnete Reproduzierbarkeit erreichen, wenn das für die Reagenszubereitung verwendete MoO3 0,2–0,5% WO3/MoO3 enthält. Falls weniger als 0,01% WO3/ MoO3 anwesend sind, kommt es zu starken Meßwertschwankungen.
