Principle and Application of Sulfides Analyzer
Water sulfides include soluble hydrogen sulfide, acid-soluble metal sulfides, insoluble sulfides and organic sulfides. The sulfides commonly measured refer to both soluble and acid-soluble sulfides. As long as the water contains 0.000 mg/L hydrogen sulfide, it will cause unpleasant smell; hydrogen sulfide is also very toxic, can harm cytochrome, oxidase, cause tissue hypoxia, and even endanger life; in addition, hydrogen sulfide can oxidize to sulfuric acid under the action of bacteria, which corrodes metal equipment and pipelines. Therefore, sulfide is an important index of water pollution.
How it works: sulfur ions react with P amino xylene amine in an acidic solution containing high iron to form Methylene blue, whose blue depth is proportional to the concentration of sulfur ions in a range of concentrations, the content of sulfide in water sample can be calculated.
It is suitable for laboratory Analyzer or industrial production process water, sewage, urban domestic sewage, river, lake, sea and other surface water testing.
