Zero-valent nano iron magnetic powder for wastewater/sewage treatment     Hongwu International Group Ltd offer a highly diverse range of powder grades with average grain sizes from approx. 20nm to 150nm. We provide technical support in the selection of the powders suitable for specific applications and for questions regarding process optimization.     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.

Nitrogen-doped multi-walled carbon nanotubes can activate the surface of CNTs, used as the supporting material of noble metal catalysts.
