Working Process

Chemical equation: 2NaOH+H2S=NA2S+2H2O NA2S+H2S=2NAHS First Step: Use sodium hydroxide liquid absorb hydrogen sulfide generate sodium sulphide Second Step: When sodium sulfide absorption saturation,continue to absorb hydrogen sulfide generate sodium hydrosulphide. Sodium hydrosulfide have 2 kinds of appearance,70%min yellow flake and 30% yellowsih liquid. We have different specs which depends on Fe content,we have 10ppm,15ppm,20ppm and 30ppm.Different Fe content,the quality is different. Sodium hydrosulfide is a compound of concern due to its environmental impact and chemical reactions. As a product of BOINTE ENERGY CO., LTD, it has good quality, preferential prices and professional export services. This compound has many advantages and is in high market demand. When it comes to the environmental impact of sodium hydrosulfide, it is important to consider its potential impact. This compound is known to have a significant impact on the environment if not handled properly. It causes water and soil contamination, affects aquatic life and poses risks to human health. Therefore, it is critical for companies like BOINTE ENERGY CO., LTD to ensure that sodium hydrosulfide is handled and disposed of responsibly to minimize its impact on the environment. In terms of chemical reactions, sodium hydrosulfide is widely used in various industrial processes. It is known for its ability to remove heavy metals from wastewater and is also used in the production of dyes and other compounds. However, it is important to note that sodium hydrosulfide can be reactive and should be handled with care to prevent any unwanted chemical reactions. Despite its environmental impact and reactivity, sodium hydrosulfide remains in high demand due to its wide range of uses. BOINTE ENERGY CO., LTD offers this product at a competitive price, making it an attractive option for industries requiring this compound. In summary, sodium hydrosulfide plays an important role in various industrial processes, but its environmental impact and chemical reactivity cannot be ignored.
