    Description / Table of Contents: Summary A method is described for the determination of sulphur in fertilisers using reduction and evolution of hydrogen sulphide followed by a potentiometric titration with lead nitrate. Several procedures are tested for the destruction of the samples. The most accurate results are obtained after dissolution of the fertiliser in hydrochloric acid.
    Notes: Zusammenfassung Die vorgeschlagene Methode beruht auf Reduktion und Entwicklung von H2S, gefolgt von einer potentiometrischen Titration mit Bleinitrat. Zum Aufschluß der Probe wurden verschiedene Verfahren getestet, wobei die Auflösung in verdünnter Salzsäure die besten Ergebnisse brachte.
