Usage

Description

POTASSIUM FERRATE(VI) 97, also known as potassium ferrate, is a dark purple glossy powder that is stable below 198°C. It is easily soluble in water, forming a light purple-red solution. Upon standing, it decomposes to release oxygen and precipitate hydrated ferric oxide. The alkalinity of the solution increases with decomposition, and it is quite stable in strong alkaline solutions, making it an excellent oxidant.

Uses

Used in Drinking Water Treatment:
POTASSIUM FERRATE(VI) 97 is used as a disinfectant for drinking water treatment, as it can quickly kill bacteria and viruses in water. It also helps remove some organic pollutants and heavy metal ions, decolorize and deodorize, and treat phenol and cyanide plating, as well as cadmium wastewater.
Used in Chemical Production:
In the chemical industry, POTASSIUM FERRATE(VI) 97 is used as an oxidizing agent to oxidize sulfonic acid, nitrite, ferrocyanide, and other inorganic substances.
Used in Zinc Smelting:
POTASSIUM FERRATE(VI) 97 is used to remove manganese, antimony, and arsenic in the process of zinc smelting.
Used in the Tobacco Industry:
In the tobacco industry, POTASSIUM FERRATE(VI) 97 is used for cigarette filters.

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.
