    Description / Table of Contents: Summary Microgram amounts of arsenic i. e. 0.1 to 20 μg, are advantageously determined photometrically by evolution of hydrogen arsenide in an suitable arsine generator and reaction with silver diethyl-dithiocarbamate in pyridine as solvent. The described modification of the method employs a sulphuric acid solution and copper-coated zinc granules. The suggested conditions of the reaction have to be observed strictly in order to obtain reproducible results. The procedure is especially well suitable for analysis of water samples.
    Notes: Zusammenfassung Mikrogrammengen Arsen von 0,1–20 μg lassen sich mit Vorteil photometrisch durch Entwicklung von Arsenwasserstoff in einem geeigneten Arsingenerator und Reaktion mit Silberdiäthyldithiocarbamidat in Pyridin bestimmen. Die angegebene Modifikation der Methode arbeitet in schwefelsaurer Lösung und unter Benutzung von verkupferten Zinkgranalien. Die Reaktionsbedingungen werden genau festgelegt und sind zur Erhaltung reproduzierbarer Ergebnisse streng einzuhalten. Das Verfahren eignet sich besonders für die Untersuchung von Wasserproben.
