Preparation of kerosene-based magnetic fluid of Fe3O4 In this experiment, analytically pure ferric chloride, ferric chloride and ammonia (NH3 content 25%) were used to prepare magnetic particles of Fe3O4 according to chemical coprecipitation method. The chemical reaction equation is 2FeCl3·6H2O+FeCl2·4H2O+8NH3·H2O= Fe3O4+8NH4Cl+24H2O (1) In the dissolution process, FeCl2·4H2O blue-green crystals a...

Nano-zero-valent iron (nZVI) nanopowder is an iron particle with a particle size between 1 and 100 nm. Its specific surface area and reactivity are much larger than ordinary iron filings and iron powder. It can be directly injected into the heavily polluted area of the water environment to form an efficient in-situ reaction zone, which can control water pollution flexibly, efficiently and at low c...

(1) Black nano Fe3O4 iron oxide: Size: 30nm, PH: 8-10, SSA:4-5g/cm3 Black nano ferroferric oxide is a mixed valence oxide of iron with a melting point of 1597°C. It is insoluble in water but soluble in acid solutions. Vk-EF01 has anti-corrosion effect. For example, the bluing of steel parts (also known as blue-burning and baking blue) is to use the oxidation effect of alkaline oxidizing solution t...
