What is Sulfide?

Sulfide is an inorganic anion of sulfur. It is a strong base and good reducing agent. Sulfides are naturally present in ground waters as a result of leaching from sulfur-containing mineral deposits. Surface waters usually do not contain high sulfide concentrations. Sulfides result from the decomposition of organic matter, bacterial sulfate reduction under anaerobic conditions, and various chemical processes. Dissolved free sulfides are very aggressive corrosives especially to metals like steel, stainless steel, and copper. Sulfides in aqueous solution are responsible for stress corrosion cracking of steel.

Sulfide Exposure and Health Risks

Sulfides readily form Hydrogen Sulfide which is a very toxic and corrosive gas. Some sulfides are highly flammable, and when they burn they produce sulfur dioxide gas.

Regulations

The EPA and CDC do not have any listed restrictions or regulations on sulfide levels

Measuring Sulfide

Dissolved Sulfide concentration in water can be measured in units of parts per million (ppm). We carry instrumental kits from CHEMetrics and monitors from ATI that determine Sulfide levels in water. All of our Sulfide products can be viewed HERE.

These Sulfide Kits are designed to accurately measure sulfide levels in water using the Methylene Blue Method.

The K-9523 Sulfide Vacu-vials Kit is used to measure sulfide levels from 0-6ppm.

K9503
The K-9503 Sulfide Vacu-vials Kit is used to measure sulfide levels from 0-3 ppm.

K9510
The K-9510 Sulfide Kit is used to measure sulfide levels from 0-1 ppm and 1-10 ppm.

K9510D
The K-9510D Sulfide VACUettes Kit is used to measure sulfide levels from 0-30 ppm and 30-300 ppm.

K9510C
The K-9510C Sulfide VACUettes Kit is used to measure sulfide levels from 0-1,200 ppm.

K9510B
The K-9510B Sulfide VACUettes Kit is used to measure sulfide levels from 0-120 ppm and 120-1,200 ppm.

K9510A
The K-9510A Sulfide VACUettes Kit is used to measure sulfide levels from 0-60 ppm and 60-600 ppm.
