| titleOfInvention | Cellulose semipermeable membrane-coated nanometer Fe3O4 solid-phase extractant and its preparation method and use |
| abstract | The invention discloses a cellulose semipermeable membrane-coated nanometer Fe3O4 solid-phase extractant and its preparation method and use. Surfaces of magnetic nanometer Fe3O4 particles are modified by a surfactant and then are coated with a cellulose semipermeable membrane so that the cellulose semipermeable membrane-coated nanometer Fe3O4 solid-phase extractant is obtained. The preparation method comprises the following steps of 1, preparing Fe3O4 magnetic nanometer particles by a coprecipitation method, 2, adding the surfactant in an aqueous solution of the Fe3O4 magnetic nanometer particles, wherein the surfactant is absorbed on the surfaces of the Fe3O4 magnetic nanometer particles by a self-assembling method, and 3, coating the cellulose semipermeable membrane on the surfaces of the Fe3O4 magnetic nanometer particles. The cellulose semipermeable membrane-coated nanometer Fe3O4 solid-phase extractant has the advantages of large adsorption capacity, fast extraction speed, simple preparation processes, good environmental benefits, strong anti-interference capability and high yield. In an applied magnetic field, the cellulose semipermeable membrane-coated nanometer Fe3O4 solid-phase extractant can be separated from a base solution conveniently. |
