Application: Absording materal, Waste water treatment, Magnetic recording material
1.Iron nanopowder in water treatment:
Because of small size, large SSA, iron nanopowder has high reactivity and very fast degradation rate of pollutants.
Iron nanopowder works well in removal of toxic metals, organic halogens, inorganic ions in water, nano-iron decolorization.
1 Removal of toxic metals
2 Removal of organic halogenated compounds
3 Removing inorganic ions from water:The principle of nano-iron removal of nitrate is mainly redox and adsorption, and its degradation kinetics has not been determined. Some scholars believe that its reaction kinetics is related to Fe / N ratio. Studies have shown that the laboratory-made nano-iron particles have high activity and can react completely with nitrates without controlling the pH value, and the effect is much better than ordinary zero-valent iron.
4 Nano iron bleaching.
2.Zero-valent nano iron magnetic powder for wastewater/sewage treatment
Zero-valent nano iron powder have certain magnetic, and under the action of magnetic field can be separated easily and quickly from the wastewater solution, can effectively remove chlorinated hydrocarbon, diphenyl ether, aromatic nitro and polycyclic aromatic hydrocarbons fluorene, etc.
The decontamination mechanism of nano iron:
1. The reduction of nano iron: the iron is active metal with reducing power, thus it can directly reduce dye into amino organic matterin in the partial acid aqueous.Because amino organic color looks light, and easy to be oxidized decomposition, so the chroma of wastewater can be reduced. Some heavy metal ions in the wastewater can be reduced by iron.
2. Micro electrolysis: Iron has electrochemical properties. Its electrode reaction product the new ecological [H] and fe2+ can make the oxidizing reduction with many components in wastewater, dyeing assistant agent can be damaged, broken, loss auxochromic ability; It can make the macromolecular material decompose into small molecule intermediates, and make some difficult biochemical degradation of chemical material become handle easily to improve the water biological properties.
3. The coagulation adsorption: Under the condition of partial acid wastewater it will produce large amounts of Fe2+ and Fe3+, when the PH value to alkaline and aerobic,ferric hydroxide hydrogen and ferrous hydroxide floc form, iron hydroxide hydrolysis could also generate ferrous hydroxide complex ion, which all have very strong flocculation performance, so original suspended solids in the waste water, and insoluble substances produced by micro electrolysis and chromaticity of insoluble substance can be adsorption condensation, hence the wastewater got the purification.
Thus, Zero-valent nano iron powder processing wastewater a comprehensive effect of reduction, micro electrolysis, coagulation adsorption.
