摘要：NOVELTY - Treating waste water by Fenton reaction, comprises (i) performing Fenton reaction by using Fenton reagent, namely ferroferric oxide nano-particle and hydrogen peroxide composition, and performing one-step synthesis by loading porous column carrier with ferroferric oxide nano-particle, and a water-soluble monomer, a water-soluble cross-linking agent, a surfactant and an initiator into a water dispersion liquid-containing ferroferric oxide nano-particles, stirring hydrophobic organic solvent and reducing agent, and polymerizing monomer; and (ii) degrading organic pollutant by Fenton reaction. USE - The method is useful for treating waste water by Fenton reaction (claimed). ADVANTAGE - The method effectively prevent the leakage of nano-particles which can be reused many times, and degrades more than 99% of organic pollutants. DETAILED DESCRIPTION - Treating waste water by Fenton reaction, comprises (i) carrying out Fenton reaction by using Fenton reagent includes ferroferric oxide nano-particles and hydrogen peroxide composition, and carrying out one-step synthesis by loading porous column carriers with ferroferric oxide nano-particles to treat waste water by adding a water-soluble monomer, a water-soluble cross-linking agent, a surfactant and an initiator into a water dispersion liquid-containing ferroferric oxide nano-particles, to obtain an aqueous phase, and then adding a hydrophobic organic solvent, and then adding reducing agent, and stirring to obtain a water-in-oil type high internal phase emulsion, and pouring the emulsion into chromatography column, and carrying out polymerization of monomers, to obtain multi-porous column material-containing ferroferric oxide nano-particles, where the amount of ferroferric oxide nano-particles in the aqueous phase, is 0.5-8 wt.%, and the water-soluble monomer is acrylamide, acrylic acid or N-isopropyl acrylamide, and the content of aqueous phase is 5-30 mole/l, and the water soluble cross-linking agent used is methylene bis acrylamide, and the mole fraction of monomer is 1-10%, and the surfactant used is Tween 85 (RTM: Polysorbate 85) or Tween 60 (RTM: Polysorbate 60), when the mass fraction of aqueous phase, is 0.5-4%, and the initiator is ammonium persulfate or potassium persulfate, when the mass fraction of the aqueous phase, is 0.2-2%, and the reducing agent is tetramethylethylenediamine or ferrous chloride, when the mass fraction of aqueous phase, is 0.03-0.1%, and the hydrophobic organic solvent used is cyclohexane, toluene or paraffin oil, when the mass fraction of emulsion, is 70-95%, and the polymerization of monomer is carried out for 0.5-12 hours, and the amount of hydrogen peroxide in waste water, is 0.5-3%; and (ii) pouring aqueous solution of organic pollutants into a chromatography column-containing polymer porous material, and adding hydrogen peroxide and ferroferric oxide nano-particles, and degrading organic pollutants by carrying out Fenton reaction.
