Chemistry

In an acidic solution, sulfide reacts with N,N-dimethyl-pphenylenediamine and ferric chloride to produce methylene blue. The resulting blue color is directly proportional to the sulfide concentration. Results are expressed in ppm (mg/L) sulfide as S.

Storage Requirements

Products should be stored in the dark and at room temperature.

Analyte-Specific Information

Sulfide is not stable in aqueous solutions, particularly at pHs below 7. Samples should be analyzed immediately after collection and agitation of the sample should be minimized.
