Detection of Reduced Sulfur in Kraft Paper
These nitrogen bubbles indicate the presence of reduced
sulfur.
Macrophotgraph
Definition/Function:
A solution of 1% sodium azide, 1% iodine, and 5% potassium iodide is a good reagent for
the detection of
sulfites, sulfides, thiocyanates, thiosulfates, and organic sulfur containing molecules.
A positive
result is indicated by the generation of nitrogen bubbles at the sulfur containing site
or over the body
of the material.
