    Description / Table of Contents: Summary The determination of arsenate using lead(II)-nitrate may be applied to the determination of arsenic in non-volatile organic substances. The titration involves following the pH-value during titration-procedure. A simple and rapid way to burn the substance is proposed. The method is not impaired by sulfate or halogenide. The standard deviation is about 0.3% As abs.
    Notes: Zusammenfassung Die Titration von Arsenat mit Blei(II)-nitratlösung durch Verfolgung des pH-Wertes der Titrationslösung läßt sich zur Arsenbestimmung schwerflüchtiger organischer Substanzen anwenden. Eine einfache und schnelle Verbrennungsmethode wird vorgeschlagen. Sulfat- und Halogenidionen stören nicht. Die Standardabweichung beträgt etwa 0,3% As abs.

    Description / Table of Contents: Summary The arsenate method may be applied to the determination of as little as 1μg arsenic; the procedure involves following the pH-value during the titration with a standard lead(II) solution. The working method and the accuracy of the procedure are given and illustrated by pertinent calculations.
    Notes: Zusammenfassung Die Arsenatbestimmung mittels einer Blei(II)-maßlösung durch Verfolgung des pH-Wertes der Probelösung während der Titration ist bis zur Bestimmung von lμg Arsen anwendbar. Die Ausführung und die Genauigkeit des Verfahrens werden angegeben und mit Berechnungen erläutert.
