Recently, Wang Xiangke, a researcher at the Laboratory of Low Temperature Plasma Applications of the Institute of Plasma, Chinese Academy of Sciences, and Hu Wenping, a researcher at the Institute of Chemistry of the Chinese Academy of Sciences, have successfully prepared a functionalized graphene material with uniform dispersion and sulfonated the material to achieve persistence. Effective removal of organic pollutants. Related research papers were published in the leading journal "Advanced Materials" in the field of materials. Graphene materials have unique physical and chemical properties and have attracted worldwide attention in recent years. Graphene and organic pollutants can produce a very strong complexation reaction, which has a strong adsorption capacity for organic pollutants. However, in solution, graphene is prone to agglomeration, which reduces its own adsorption capacity. Wang Xiangke and Hu Wenping have shown through a large number of experimental studies that the functionalization of sulfonic acid on the surface of graphene can not only improve the dispersibility of graphene, but also improve the adsorption capacity of graphene. The results show that the functionalized graphene has an adsorption capacity of naphthalene and naphthol of 2.4 mmol per gram, which is the highest adsorption capacity. At present, the preparation cost of this kind of material is relatively high, but with the development of technology, it is expected to achieve low-cost, large-scale preparation, so it has very important application prospects in future environmental pollution control. Wang Xiangke said that the study found that graphene oxide has a good adsorption effect on metal ions after oxidation of graphene and modification of oxygen-containing functional groups on its surface. In addition, in the research of plasma technology to prepare graphene nanomaterials, the research group can directly remove graphene from the surface of graphite by plasma technology, which does not require chemical reagents, simplifies the preparation process, and the process is environmentally friendly. According to reports, the common graphite is formed by stacking a layer of planar carbon atoms arranged in a honeycomb order. The interlayer force of graphite is weak, and it is easy to peel off each other to form a thin graphite sheet. When the graphite sheet is peeled off into a single layer, the single layer having only one carbon atom thickness is graphene.
