Principle of potassium ferrate water purification
Will potassium ferrate meet the formed 4Fe(OH) first? The color is reddish brown, and it is flocculent precipitation, which has adsorption effect and will adsorb impurities in water. The principle of disinfection and sterilization is the oxidation of potassium ferrate. The highest redox voltage of potassium ferrate is 2.2V, which is second only to the oxidation of fluorine gas and higher than chlorine dioxide, chlorine gas, sodium hypochlorite, hydrogen peroxide and potassium permanganate.

Other applications of potassium ferrate: 1. Potassium ferrate is used for fish pond aquaculture water treatment;

Potassium ferrate can increase dissolved oxygen in water, and has a good removal effect on ammonia nitrogen, nitrite and algae in water. It can be used to remove fulvic acid, suspended solids and eutrophication in fresh water. It has a unique effect on sterilization, disinfection and purification of water.

2. Potassium ferrate is used for marine pollution control;

It is reported that the application of potassium ferrate and peroxide as a non-toxic and harmless marine antifouling agent in marine environment purification, when their mass is 2× 65,438+00-8 and 3× 65,438+00-7 respectively, shows almost 65,438+000% antifouling effect, and its good synergistic effect is far superior to that of single use.

3. Potassium ferrate is used for the recycling of swimming pool water: because of its superior performance in water purification, it can be used for the recycling of swimming pool water. It not only sterilizes and removes the dirt and suspended matter brought by human body, but also has no harm and stimulation to human body, is safe and tasteless, and is convenient to add, so it is very suitable for replacing chlorine gas for disinfection, purification and recycling of swimming pool water.

4. Potassium ferrate is used to treat radioactive wastewater and remove arsenic and cyanide ions.

Compared with other arsenic removal materials, potassium ferrate has the advantages of simplicity, good effect, less sludge and no secondary pollution. For high arsenic drinking water, as long as the dosage of potassium ferrate and the arsenic concentration of raw water reach 15: 1 above, the arsenic residue in the treated water sample can meet the national drinking water hygiene standard.
