39469-86-8 - Uses and synthesis methods
use
1. As a water-soluble fungicide, potassium ferrate 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, hinder the growth and reproduction of microorganisms, and play a role in killing algae and sterilizing bacteria.
2. As a new non-nitrogen high-efficiency disinfectant, it is used for drinking water treatment and can quickly kill bacteria and viruses in the water; remove some organic pollutants and heavy metal ions in the water, decolorize and deodorize, and condense circulating water Control the generation of biological scale and treat wastewater containing phenol and cadmium cyanide. Oxidized starch is prepared for paper surface sizing and textile finishing. In chemical production, it is used to oxidize sulfonic acid, nitrite, ferrocyanide and other inorganic substances. Used to remove manganese, antimony and arsenic during zinc smelting. In the tobacco industry, it is used for cigarette filters, etc.
3. Ferrate is a new type of bactericidal and algicidal agent with excellent disinfection performance of oxidizing bacteria. The generated Fe(OH)3 has adsorption effect on various anions and anions, and is non-toxic and non-polluting. It is suitable for disinfection of drinking water and disinfection of circulating cooling water system. It is also suitable for the treatment of CN-containing wastewater.

production method
1, hypochlorite oxidation method
NaOH is added to the reaction kettle, dissolved in water and cooled to 20 ℃, and the chlorine gas is fully saturated. Then filter to remove solid NaCl. The filtrate is reserved (the wave is sodium hypochlorite solution with effective chlorine content of 70% ~ 80%).
transfer the filtrate to the oxidation reactor, and add Fe(NO3)3 solution dropwise while stirring at 20~30 ℃. After a period of reaction, samples were taken to measure the end point. When [Fe3 +}<0.5 mg/ml in the reaction solution is the end point of oxidation. After reaching the finish line, continue stirring for another hour. Then add 40% aqueous solution, and filter the precipitated NaCl to remove after resting. The filtrate is standby.
transfer the filtrate to the conversion kettle, add 50% KOH aqueous solution, and react at 20~30 ℃ for 2 hours. The precipitated brown-purple precipitate is K2FeO4. Filter, wash the filter cake with ice water and glycerol, vacuum dry, and pack.
the high temperature sodium peroxide method puts sodium peroxide and ferrous sulfate into the reaction kettle in turn, and the feeding ratio is 3: 1(mol). In a closed reactor, in a nitrogen stream, the reaction is heated and reacted at 700°C for one hour. Na2FeO4 powder is obtained, dissolved in NaOH solution, and filtered quickly. The filtrate is transferred to the conversion kettle, and equimolar KOH solid is added to precipitate K2FeO4 crystal. Wash with 95% ethanol and vacuum dry to obtain the finished product.
2. By chemical oxidation method, chlorine gas is passed into human sodium hydroxide solution to generate saturated sodium hypochlorite concentrated alkali solution, iron nitrate is slowly added for oxidation reaction to generate sodium ferrate, potassium hydroxide is used to convert into potassium ferrate, and the crude product is filtered by suction, and then Dissolve with potassium hydroxide, recrystallize, decalinate with benzene and 95% ethanol, wash with ether, and dry to prepare potassium ferrate products, which.
electrolytic method will iron trichloride and sodium hydroxide solution, in a diaphragm electrolytic cell, with iron anode electrolytic oxidation, into iron oxidation monohydroxide complex, in the presence of halogen ions, electrochemical conversion of high ferrate ions, combined with Na +>^ to form sodium ferrate, the content can reach 50~80g/L. With 50% potassium hydroxide solution, according to the molar ratio of potassium hydroxide to sodium ferrate 3:1 reaction to generate potassium ferrate, suction filtration, with isopropanol alkalization, washing, drying to obtain potassium ferrate, put in a closed dryer stored.
