Study on preparation technology and characterization of ferrate
The process of ferrate preparation was established by hypochlorite oxidation.The effects of ferrate type,reaction time,reaction temperature,raw material ratio and alkali addi-tion on the yield and purity of ferrate preparation were discussed.The results show that the yield and purity of ferrate are 38.2%and 88.7%,respectively,when the reaction temperature is 20℃,the reaction time is 75 min,and the molar ratio of Fe3+to NaClO is 0.2∶1.0.The addition of base has no obvious effect on the yield and purity of ferrate.The product was characterized by UV-VIS absorption spectrum and infrared spectrum.The results showed that the product was potassium ferrate.
