    Description / Table of Contents: Zusammenfassung S2− kann mit Jodnitrotetrazoliumchlorid (INT) innerhalb von 30 min photometrisch bestimmt werden. PO4 3−, Cl− und SO4 2− in Konzentrationen bis zu 5 · 10−2 mol/l, S2O3 2− bis zu 10−4 mol/l und S3O6 2− bis zu 2 · 10− mol/l stören nicht. Die untere Bestimmungsgrenze beträgt 3,4 · 10−5 mol/l, entsprechend 1 μg S2−. Als relative Standardabweichung ergibt sich bei der Bestimmung von 3,2 μg S2}±6,4 Rel.%.
    Notes: Summary The proposed photometric method is based on the reaction of S2− with iodo-nitro-tetrazolium chloride (INT). PO4 3−, Cl− and SO4 2− up to concentrations of 5 · 10−2 mol/l, S2O3 2− up to 10−4 mol/l and S3O6 2− up to 2 · 10−4 mol/l do not interfere. It is possible to determine S2− down to concentrations of 3.4 · 10−5 mol/l, corresponding to 1 μg of S2−, within 30 min. The relative standard deviation in the case of 3.2 μg of S2− is ±6.4% rel.
