对Hummers法制备的氧化石墨烯进行碱处理去除表面的氧化碎片，经盐酸质子化和3-氨丙基三乙氧基硅烷硅烷化，与溴代正丁烷反应制备出表面带正电荷的铵盐功能化氧化石墨烯（PAS-bwGO），通过傅里叶红外光谱、拉曼光谱、X射线光电子能谱、场发射扫描电镜、透射电镜对其进行表征分析，并初步用于去除水中六价铬Cr（VI）的研究.结果表明，制备的铵盐功能化氧化石墨烯对Cr（VI）有很高的吸附性能，初步测得其饱和吸附量达到102 mg/g.

Graphene oxide prepared by Hummers method was firstly washed by alkali solution to remove oxide debris ad-hered on the surface, then was modified through protonation with hydrochloric acid, silanization reaction with (3-aminopropyl)triethoxysilane and quaternization reaction with N-butyl bromide to produce positive charged primary amine salt functionalized graphene oxide (PAS-bwGO). PAS-bwGO was characterized and analyzed by Fourier transform infrared spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, field emission scanning electron microscopy and transmission electron microscopy, and was used preliminary for removal of chromium(VI) in aqueous solution. Results showed that the prepared PAS-bwGO had a high capacity of chromi-um(VI) adsorption, and the maximum adsorption capacity could reach 102 mg/g.
