| titleOfInvention | Preparation method and application of photo-Fenton self-cleaning film |
| abstract | The invention belongs to the technical field of preparation of environment functional materials, and particularly relates to a preparation method and application of a photo-Fenton self-cleaning membrane; the method comprises the following steps: firstly, pre-soaking a polyvinylidene fluoride membrane by using ethanol, and then soaking the polyvinylidene fluoride membrane in a tannic acid aqueous solution to obtain a membrane marked as a PVDF/TA membrane; washing with deionized water, transferring to ferric trichloride hexahydrate aqueous solution for soaking, washing, and drying to obtain PVDF/TA-Fe (III) membrane; immersing in a ferric trichloride hexahydrate aqueous solution, incubating under a certain water bath temperature condition, taking out the membrane, rinsing with deionized water, and drying to obtain a self-cleaning membrane material which is marked as PVDF/TA/beta-FeOOH; the invention couples the light-Fenton reaction with the membrane separation technology, thus improving the anti-fouling performance of the membrane; and different oil-water emulsions can be efficiently separated, the recovery rate of the membrane flux is up to more than 98% in 10min, the service life of the membrane is prolonged, and the cost is reduced. |
