| titleOfInvention | A tyrosine-modified ferroferric oxide magnetic nano-adsorption material and its preparation method and application |
| abstract | The invention relates to a tyrosine-modified ferroferric oxide magnetic nanometer adsorption material, a preparation method and an application thereof, and belongs to the field of wastewater treatment. The ferroferric oxide magnetic nano-adsorption material (molecular formula is as follows) modified by tyrosine in the present invention has advantages such as large specific surface area, high saturation magnetic susceptibility, large adsorption capacity, due to the introduction of tyrosine, the structure of magnetic material contains both amide and carboxyl groups, so under suitable pH conditions, this material can effectively remove anionic dyes (such as methyl orange) and cationic dyes (such as methylene blue). The preparation method of the tyrosine-modified ferric iron tetroxide magnetic nano-adsorption material provided by the invention has mild conditions, simple process, short production cycle and easy realization of large-scale industrial production. The saturation magnetization of the product is as high as 49.06emu/g. After the dye wastewater is treated, the adsorption material can be quickly recovered and recycled by applying an external magnetic field, which has a high application prospect. |
