Sulfide ion is found in groundwaters and wastewater causing odor and corrosion problems. If acidified, these waters can release hydrogen sulfide, which is extremely toxic even at low levels. Sulfide can be oxidized to sulfuric acid and so can cause rapid deterioration of concrete infrastructure. This test method provides a means for interference-free measurement of free sulfide ion.
The title and scope are in draft form and are under development within this ASTM Committee.
