NOVELTY - Graphene oxide fatty ethylenediamine removing agent comprises 0.1-5 g/litre of oxidized graphene suspension. USE - Graphene oxide fatty ethylenediamine removing agent. ADVANTAGE - The graphene oxide fatty ethylenediamine removing agent is cost effective, which is directly used for removing amine, has good absorbing performance and simple solid liquid separation and suitable for industrialization in an effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using graphene oxide fatty ethylenediamine removing agent, which involves: (A) taking natural graphite as raw material; (B) using hummer method to prepare graphene oxide suspension; (C) taking waste water containing fatty ethylenediamine as the object of processing; (D) mixing graphene oxide suspension and waste water uniformly to obtain mixed liquid; (E) oscillating the mixed liquid; (F) adsorbing and removing; (G) stirring the floated oxidized graphene; (H) recycling air for adsorption reaction of the oxidized graphene to obtain hydrophobic flocculant; and (I) removing the purified water of the fatty amine.
