POTASSIUM FERRATE(VI) 97 39469-86-8

Potassium ferrate is a dark purple glossy powder. Stable in dry air below 198℃. It is easily dissolved in water and becomes a light amaranth solution. When left alone, it will decompose and release oxygen, and precipitate iron trioxide (iron oxide). The alkalinity of solution increases with decomposition. It is quite stable in strongly alkaline solution and is an excellent oxidant. It has an efficient disinfection effect. It has stronger oxidation than potassium permanganate.

1. Potassium ferrate has become a new green water treatment material

Potassium ferrate is a compound containing FeO42 -, its central atom Fe to hexavalent exist, under the condition of acid and alkaline conditions of standard electrode potential respectively E0FeO42 - / Fe3 + = 2.20 V, E0FeO42 - / Fe (OH) 3 = 0.72 V, therefore, no matter in acidic condition, or under the condition of alkaline ferrate salt with a strong oxidation, oxidation, can be widely used in water and wastewater disinfection and sterilization. Therefore, ferrate is a new type of water treatment agent with high efficiency and non-toxicity. In the process of drinking water treatment, the comprehensive performance of eight characteristics as a whole, including oxidation, adsorption, flocculation, precipitation, sterilization, disinfection, decolorization, deodorization, is incomparable to other water treatment agents. PH in 6-6.5, k2feo46mg-10mg per liter of water, at room temperature for 30 minutes can kill pathogenic bacteria, e. coli, typhoid bacteria and virus removal rate of 99.5%-99.95% above, no odor palatability, up to safe drinking standards. This product shows super strength in water treatment series.

2. Potassium ferrate is used in the treatment of industrial wastewater and municipal sewage

K2FeO4 for BOD and COD in waste water, such as lead, cadmium, sulfur, have good removal effect, 10 mg, 20 mg/L of potassium ferrate oxidation 96% of BOD, remove the 86% 75% of ammonia nitrogen and phosphorus, PH5.5, raw water turbidity is 28 degrees, under the condition of residual turbidity after (sink) 30 mg/L of potassium ferrate, can remove the water trichloroethylene 85.6%, naphthalene removal rate of 100%, potassium ferrate good flocculation effect, in the process of the performance and the function of the pollutants in the water, through a series of reactions, by hexavalent fell to trivalent, with different charge in the middle of the state, such as: Fe (Ⅴ)/Fe (Ⅵ) and so on, and gradually be restored into a flocculation Fe (Ⅲ). It has good application potential in printing and dyeing, leather making, printing, paper making, pharmaceutical, petroleum and petrochemical industries. The unique effect of this product in water purification is to play a synergistic role of oxidation, adsorption, flocculation, precipitation, sterilization, disinfection, decolorization and deodorization at the same time, without producing any toxic or harmful substances. Using multi-functional compound agent to strengthen and broaden the water purification efficiency of the current conventional water treatment process can not change the existing process and do not add large auxiliary facilities.
