The method can be used for a variety of waters and wastewaters. Applicable Concentration Range. 0.1 to 20.0 mg-S 2- /L (See 4500-S2- A) Interferences. Strong reducing agents interfere in the methylene blue method by preventing formation of the blue color. Thiosulfate at concentrations about 10 mg/L may retard color ...
WebSummary of Method Hydrogen sulfide and acid-soluble metal sulfides react with N,N-dimethyl-p-phenylenediamine sulfate to form methylene blue. The intensity of the blue color is proportional to the sulfide concentration. High sulfide levels in oil field waters may be determined after proper dilution. Test results are measured at 665 nm.
