COLORIMETRIC DETERMINATION OF MANGANESE IN ANOXIC WATERS1
Open accessAbstract
In the reducing environment of anoxic basins manganese (III) or (IV) is reduced to soluble Mn (II); the deep waters of the Black Sea contain up to 500 µ g Mn (II)/ liter, about 100 times the oceanic average. When this manganese was measured with formaldoxime, color development was erratic if the reagents were added separately. Rapid and reproducible color development was achieved by using a mixed ammonia/formal‐doxime reagent added singly to the sample. Precipitation was avoided by maintaining the pH in the range 8.8–8.9. No interferences from sulfide or dissolved salts were observed. A small correction was made for interference due to iron. Dissolved manganese values in the Black Sea ranged from a midwater maximum of ca. 460 µ g Mn/liter to ca. 250 µ g/ liter in deep water.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
