Anthroquinone / reduced graphene oxide mediator membrane, and preparation method and use thereof

Abstract

The present disclosure belongs to the field of water treatment, and particularly relates to an anthroquinone / reduced graphene oxide mediator membrane, and a preparation method and use thereof. The anthroquinone / reduced graphene oxide mediator membrane includes a membrane matrix and an aminoimidazopyridine-modified reduced graphene oxide dispersed in the membrane matrix. A material of the membrane matrix is a composite of polyamide and anthraquinone-modified polysiloxane. The aminoimidazopyridine-modified reduced graphene oxide is a reduced graphene oxide with a 6-aminoimidazo[1,2-A]pyridine bonded to a surface thereof. The anthroquinone / reduced graphene oxide mediator membrane provided by the present disclosure had a high initial nitrogen removal rate and a high time-dependent nitrogen removal rate.
