Uses and synthesis of Potassium Ferrate powder

Potassium Ferrate powder is an excellent oxidizing agent. It is a new type of non-nitrogenous high-efficiency disinfectant with high disinfection effect. It is mainly used for drinking water treatment.

In chemical production, Potassium Ferrate CAS 39469-86-8 is used as oxidizing agent for sulfonic acid, nitrite, ferrocyanide and other inorganic substances, and in zinc refining, Potassium Ferrate Raw Materials is used to remove manganese, antimony and arsenic, and is used for cigarette filters in tobacco industry.

Applications / Functions of Potassium Ferrate powder

1. As a kind of water-soluble bactericide, Potassium Ferrate powder can destroy the cell wall, cell membrane and some substances in the cell structure of microorganisms (such as enzymes) through strong oxidation, inhibit the synthesis of proteins and nucleic acids, and impede the growth and reproduction of microorganisms, so as to play the role of algaecide and sterilization.
2. Potassium Ferrate Raw Materials as a new type of non-nitrogen high-efficiency disinfectant for drinking water treatment, can quickly kill bacteria and viruses in the water; remove some organic pollutants in the water, heavy metal ions, decolorization and deodorization, condensation of circulating water to control the generation of bio-sticky scale and the treatment of phenol-containing, cyanide cadmium plating wastewater and so on. Produced oxidized starch, Potassium Ferrate CAS 39469-86-8 for paper surface sizing and textile finishing.

In chemical production, Potassium Ferrate CAS 39469-86-8 is used to oxidize sulfonic acid, nitrite, ferrocyanide and other inorganic substances. It is used to remove manganese, antimony and arsenic in zinc refining. In the tobacco industry, Potassium Ferrate powder is used in cigarette filters.

Physicochemical Property of Potassium Ferrate powder

• Potassium Ferrate CAS 39469-86-8 is dark purple glossy powder, stable below 198℃. It is very soluble in water and becomes light purple-red solution, after standing, it will decompose and release oxygen, and precipitate hydrated iron trioxide.
• The alkalinity of the solution increases with decomposition, and it is quite stable in strong alkaline solution, which is an excellent oxidizer. It is an excellent oxidizing agent. It has a highly efficient disinfection effect.

Production methodprocess of Potassium Ferrate powder

Chemical oxidation method will be chlorine through the sodium hydroxide solution to generate saturated sodium hypochlorite concentrated alkaline solution, slowly add ferric nitrate oxidation reaction to generate sodium pertechnetate, with potassium hydroxide into Potassium Ferrate powder, filtration to get the crude, and then dissolved in potassium hydroxide, recrystallization, with benzene and 95% ethanol for dealkalization, ether washing, drying to get Potassium Ferrate Raw Materials, which can be used immediately. Ferrate Raw Materials can be used immediately or stored in air-insulated containers.

Electrolysis method will be ferric chloride and sodium hydroxide solution, in the diaphragm-type electrolysis tank, with an iron anode electrolytic oxidation, Mr. Iron oxide hydroxide complex, in the presence of halogen ions, electrochemical conversion to ferric ferritic acid salt ions, and Na + > ^ combined into sodium ferritate, the content of which can be up to 50-80g / L.

Use 50% potassium hydroxide solution, according to the molar ratio of potassium hydroxide and sodium pertechnetate 3:1 reaction to generate potassium pertechnetate, filtration, dealkalization with isopropyl alcohol, washing, after drying to obtain Potassium Ferrate CAS 39469-86-8, put into the airtight drier for storage
