β- cyclodextrin - graphene oxide - Preparation and Application of Celite Composites

The present invention belongs to the field of synthetic polymer composite materials, to β- cyclodextrin - Preparation of diatomaceous earth composite materials, particularly to a β- cyclodextrin - Preparation and Application of diatomaceous earth composite material - graphene oxide. One kind β- cyclodextrin - graphene oxide - preparation of a composite material of diatomaceous earth, using a modified Hummers to have legal graphene oxide, and then the graphene oxide β- cyclodextrin and isophorone diisocyanate β- cyclodextrin was obtained under the action of a crosslinking agent - graphene oxide powder, then β- cyclodextrin - ultrasonic mixing diatomite powder and pre-graphene oxide, the finally obtained β- cyclodextrin - oxidation graphene - diatomite composite (β-CD-GO-DE). The method according to the present invention is prepared as an adsorbent material for adsorption of methylene blue objects, test results show that the composite material has a better adsorption effect, the use of a dye material handling sewage with a simple procedure, the adsorption rate features, there are some practical value.
