ASTM WK77585

New Test Method for Available Sulfide in Water by Gas Extraction

1. Scope

This test method specifies a method for the determination of available sulfide in water and wastewater in mass concentrations ranging from 0.04 to 4000 mg/L. Reduction of the volume of the water sample applied allows the determination of higher mass concentrations

Keywords

HS-; H2S; Na2S; hydrosulfide; thioacetamide; electrochemical; dissolved; undissolved; groundwaters

Rationale

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.
