| | POTASSIUM FERRATE(VI) Usage And Synthesis |
| Description | Pure potassium ferrate is a dark purple glossy powder,stable below 198°C. It is easily soluble in water to form a light purple-red solution. After standing, it will decompose to release oxygen and precipitate hydrated ferric oxide. The alkalinity of the solution increases with decomposition, it is quite stable in strong alkaline solution, and it is an excellent oxidant. | | Applications | As a new type of non-nitrogen efficient disinfectant, potassium ferrate is used for drinking water treatment, which can quickly kill bacteria and viruses in water; remove some organic pollutants and heavy metal ions in water, decolorize and deodorize, and treat phenol and cyanide plating. Cadmium wastewater, etc. 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 for cigarette filters, etc. | | Synthesis | Potassium ferrate can be synthesized by chemical oxidation:Pass the chlorine gas into the sodium hydroxide solution to generate saturated sodium hypochlorite concentrated alkali solution, slowly add ferric nitrate for oxidation reaction to generate sodium ferrate, convert it into potassium ferrate with potassium hydroxide, suction filtration to obtain the crude product, then dissolve with potassium hydroxide and recrystallize. , with benzene and 95% ethanol for dealkalization, ether washing and drying. It can be used immediately or stored in an airtight container. |
