Abstract

The invention discloses a graphene oxide waste conversion and recovery device and a method thereof. The graphene oxide waste conversion and recovery device comprises an anode reaction assembly and a cathode reaction assembly, the anode reaction assembly comprises an anode reaction chamber and a first electrode, the first electrode is installed in the anode reaction chamber and used for being connected with a power source anode, and the cathode reaction assembly comprises a cathode reaction chamber and a second electrode. The second electrode is installed in the cathode reaction chamber and used for being connected with a power source cathode. According to the graphene oxide waste conversion and recovery device, graphene waste recovery is achieved through an electrochemical method, on one hand, dispersed high-viscosity graphene oxide is efficiently converted and recovered into self-agglomerated and easily-separated graphene; on the other hand, any other chemical medicine is not needed, harmful substances to the environment are not generated, green and pollution-free effects are achieved, and the problems of high cost, environmental unfriendliness, secondary pollution, difficulty in recovery, complicated post-treatment and the like of a chemical treatment method in the traditional technology are solved.

Description

technical field [0001] The invention relates to the field of graphene waste treatment, in particular to a graphene oxide waste conversion and recovery device and a method thereof. Background technique [0002] With the increasing application of graphene oxide, a large amount of graphene oxide waste (including sewage) will inevitably be generated during the large-scale production of graphene oxide. Due to the unstable properties of graphene oxide waste, difficult determination of solid content, high slurry viscosity, poor consistency, and large cleaning water consumption, the cost of graphene oxide waste treatment is relatively high and the treatment has certain pollution. At present, the general treatment methods of graphene oxide waste include: flocculant flocculation treatment and reducing agent reduction treatment. The above methods have problems such as high cost, unfriendly to the environment, secondary pollution, difficult recovery and complex post-processing. SUMMAR...
