Preparation method and application of strong adsorption type ultrafiltration membrane |
| abstract |
The invention provides a preparation method and application of a strong adsorption type ultrafiltration membrane, wherein the preparation method comprises the steps of preparing the ultrafiltration membrane and an adsorption membrane, activating the ultrafiltration membrane and the adsorption membrane by adopting electron beam irradiation modification, and carrying out grafting modification by utilizing a surfactant, so that the ultrafiltration membrane and the adsorption membrane can be combined, and the adsorption capacity and the hydrophilic performance of the ultrafiltration membrane and the adsorption membrane on heavy metal ions are improved. |
