| titleOfInvention | Composite magnetic nano catalytic material for water treatment and preparation and application thereof |
| abstract | The invention relates to the technical field of environmental protection technology and functional materials, in particular to a preparation method of a composite magnetic nano catalytic material for water treatment and application of the composite magnetic nano catalytic material in catalytic oxidation treatment of wastewater. Firstly, mixing ferrous salt and ferric salt according to a certain proportion, adding polyethylene glycol, sodium gluconate, ammonium citrate and the like as synthesis aids, and preparing magnetic Fe under alkaline conditions 3 O 4 A nanoparticle; subsequently, Fe 3 O 4 The nanometer particles are treated by dilute acid and Cetyl Trimethyl Ammonium Bromide (CTAB) solution and then mixed with magnesium ions to prepare magnetic Mg (OH) under the regulation of alkali liquor 2 @Fe 3 O 4 Composite nanoparticles; finally, the prepared composite magnetic nano material is immersed in an active metal ion solution to promote the formation of lattice defect active sites, and further enhance the catalytic oxidation effect. The obtained magnetic composite nano catalytic material has stable property, simple preparation process and cheap and easily obtained raw materials, and is a multipurpose environment-friendly material. |
