Abstract

In this study, the reduced graphene hydrogel rGH with three-dimensional structure was prepared by chemical reduction method, that the adsorption and removal performance of heavy metal Cr (VI) in water was discussed. Graphene hydrogel is capable of high specific surface area, three-dimensional structure and narrow pore size distribution. Moreover, there are a large number of oxygen-containing functional groups such as hydroxyl groups on the surface of the material. Graphene hydrogel can remove Cr (VI) in water efficiently and continuously, and the removal of Cr (VI) in 1 ppm can keep over 99.5% in 6 hours, indicating the excellent application.
