The present paper reports a high effective adsorbent graphene oxide (GO) oxidized by NaClO. Its ability to separate cationic dye rhodamine (RhB) from aqueous solution was investigated. The adsorption of RhB onto GO can reach adsorption equilibrium within a short time, and the adsorbent exhibits excellent removal efficiency, which suggests its potential application value in removing dye from waste water.
