Potassium ferrate is an excellent oxidant with high disinfection efficiency, and it is a new type of non-nitrogen efficient disinfectant, mainly used for drinking water treatment.

I. Application of Potassium Ferrate

1. Potassium ferrate as water treatment agent

Ferrate and its reduced iron have strong oxidizability, which can oxidize and decompose various organic pollutants without producing harmful substances. At the same time, its own reduction product Fe(OH)3 has adsorption and flocculation functions, which can help remove ten kinds of organic pollutants. Therefore, when potassium ferrate oxidizes organic matter, it mainly shows strong oxidation and flocculation.

2. Potassium ferrate is the positive active material of alkaline battery.

In 1999, Israeli scientists used potassium ferrate as cathode active material, and used decaaqueous solution system and non-aqueous solution system to manufacture ultrairon batteries. Its structure is similar to that of the traditional alkaline zinc-manganese battery, except that potassium ferrate is used as the cathode material instead of manganese dioxide in the zinc-manganese battery, but its performance is higher discharge capacity and discharge voltage, and Fe has a certain dynamic reversibility from trivalent to hexavalent.

3. Other applications

Potassium ferrate can be used for aquaculture water treatment in ten fish ponds. It can increase dissolved oxygen in water and has a good removal effect on ammonia nitrogen, industrial nitrate and algae in water. 10% can remove humic acid and suspended matter in water and prevent eutrophication of fresh water. It has a unique effect on fire bacteria, disinfection and water purification. Potassium ferrate can also be used to prevent the pollution of ten oceans.
