As a new non-nitrogen high-efficiency disinfectant , used for drinking water treatment, it can quickly kill bacteria and viruses in the water, remove some organic pollutants and heavy metal ions in the water, decolorize and deodorize, condense circulating water to control the generation of biological scale, and treat phenol-containing, cyanide cadmium plating wastewater, etc. . Oxidized starch is prepared and used for paper surface sizing and textile finishing. In chemical production, it is used to oxidize sulfonic acid, nitrite, ferrocyanide and other inorganic substances. It is used to remove manganese, antimony and arsenic in zinc smelting. In the tobacco industry, it is used in cigarette filters, etc.
Usage Ferrate is a new type of bactericidal algaecide, which has excellent disinfection performance of oxidizing bacteria. The generated ferrate has adsorption effect on various anions and cations, and is non-toxic and non-polluting. Suitable for drinking water disinfection and sterilization of circulating cooling water systems. It is also suitable for the treatment of wastewater.

Production method Hypochlorite oxidation method
Add it into the reaction kettle, add water to dissolve it, then cool it to ℃, and pass chlorine gas to fully saturate it. Then filter to remove solids. The filtrate is reserved for later use (the wave is a sodium hypochlorite solution with an effective chlorine content of ~).
Transfer the filtrate to the oxidation reaction kettle, and add the solution dropwise while stirring at ~°C. After a period of reaction, samples were taken to measure the end point. When [+}< in the reaction solution is the end point of oxidation. After reaching the end point, continue stirring for another hour. Then add the aqueous solution and filter it out after standing still. The filtrate is reserved. Transfer the filtrate to the conversion kettle, add the aqueous solution, and react at ~°C. This is the brownish purple precipitate that precipitates. Filter, wash the filter cake with ice water and glycerol, vacuum dry, and package. High-temperature sodium peroxide method: Put sodium peroxide and ferrous sulfate into the reaction kettle in sequence, and the feeding ratio is: Close the reactor, heat the reaction in a nitrogen flow, and react at ℃ for one hour. The powder is obtained, dissolved in solution and filtered quickly. The filtrate is transferred to the conversion kettle, and equal moles of solid are added to precipitate crystals. Wash with ethanol and dry in vacuum to obtain the finished product.
