Description
Summary:At room temperature, reduction with tin(II) and aeration, are suitable for quantitative separation of microgram quantities of mercury (II) from sulfuric and nitric acid solutions over wide ranges of concentrations Mercury is concentrated during the separation, and is determined by a direct photometric dithizone procedure. This technique is applicable for 0.10 μg mercury per sample charge with a standard deviation for a single determination of 0.05 μg mercury in the o to 0.5 μg range. Une méthode de concentration (par réduction et aération) est décrite en vue du dosage photométrique de traces de mercure, au moyen de dithizone. Beschreibung einer photometrischen Methode zur Bestimmung von Quecksilber in Spurenmengen mit Dithizon. Die Abtrennung aus sauren Lösungen erfolgt nach Zusatz von Zinn-(II)-chlorid mit Hilfe eines Luftstromes.
