The invention discloses immobilized polymer microsphere of a kind of nano-iron oxide and preparation method thereof, by glycidyl methacrylate, acrylic acid, crosslinking agent, sodium peroxydisulfate, iron chloride, the raw materials such as flyash are made, the present invention utilizes synthesis in water nano-iron oxide, expand pollutant absorbed species, improve the adsorption to heavy metal, polymer microsphere is prepared by free radical emulsion on this basis, disperse ferriferous oxide being entrenched in microballoon by solution, so as to establish heavy metal adsorption passage, obtain multiple binding sites, the polymer microsphere of bigger serface, it can realize that the pollutants such as heavy metal are efficient, stablize, lasting adsorbing and removing, it is that a kind of preparation method is simple, synthesize the low ecotopia of cost and administer material. |
