Abstract
The invention relates to a method for removing pollutants in water body under synergistic effect of graphene oxide (GO) adsorption and photosensitized oxidation. The method mainly comprises the following steps: adsorbing the pollutants on the surface of GO by utilizing rich oxygen-containing functional groups on the surface of GO and under the action of pi-pi conjugation and a hydrogen bond, producing strong oxidizing reactive oxygen (ROS) species such as.OH, <1>O2,.O2<-> and the like through two ways, namely Type-I and Type-II, when the GO taken as a photosensitizer is irradiated by a white LED lamp, and further degrading the pollutants in the water body. Besides, the GO has good stability and can be used repeatedly. The method provided by the invention has the characteristics of simple operation, speediness, efficient removal and wide application range, and sunlight is hopeful to be utilized for the actual water sample treatment.
