| titleOfInvention | Preparation method and application of ethylenediamine grafted graphene oxide modified polyurethane carrier |
| abstract | The invention provides a preparation method and application of an ethylenediamine grafted graphene oxide modified polyurethane carrier. The method comprises the following steps: adding the polyurethane carrier subjected to ultraviolet radiation into an ethylenediamine aqueous solution, carrying out heating reaction, washing the product after the reaction with deionized water, and drying to obtain the polyurethane carrier grafted with ethylenediamine; and placing the polyurethane carrier grafted with the ethylenediamine into the graphene oxide dispersion liquid, and carrying out heating reaction to obtain the ethylenediamine-grafted graphene oxide modified polyurethane carrier. According to the preparation method provided by the invention, the graphene oxide modified and reduced by ethylenediamine has a large specific surface area and a porous structure, so that the damage of cells caused by fluid shear force in the attachment growth process of microorganisms can be relieved, the attachment and spreading process of the cells on the surface of a carrier is shortened, and a biological membrane is easy to form quickly; in addition, the preparation method has the characteristics of simple process, stable performance, short membrane hanging time of the modified carrier and the like, and has good application prospect in the field of sewage treatment. |
