Graphene oxide has potential application prospects in the field of environmental protection as the adsorption material of uranium containing wastewater due to its many advantages such as its large specific surface area, high mechanical strength and good chemical stability, which has attracted much attention. The research situation and progress of uranium adsorption of graphene oxide composite ma terials were summarized in this paper. The principle about effect of solution pH value, temperature, ionic strength, contact time and adsorbent dosage on uranium adsorption by graphene oxide composite materials was analyzed. The study on internal relationship between the microstructure and micromor phology of graphene oxide composite materials and uranium adsorption capacity by the methods of sur face complexation model, spectral analysis and theoretical calculation was elaborated. Meanwhile, the challenges in the study of the adsorption of uranium by graphene oxide composite materials were stud led, the research on the interaction mechanism of uranium and graphene oxide materials and their de velopment and application in environmental protection were prospected.
