Abstract

The invention provides a copper-based three-dimensional graphene material and a method for treating unsymmetrical dimethylhydrazine wastewater by using the same, so as to solve the environmental pollution problem caused by unsymmetrical dimethylhydrazine wastewater. The copper-based three-dimensional graphene material includes: preparing a graphene oxide stock solution; adding copper salt to the graphene oxide stock solution; ultrasonically treating the mixed solution; heating the mixed solution at a constant temperature; dehydrating to form a copper-based three-dimensional graphene material . The present invention utilizes the copper-based three-dimensional graphene composite material to treat unsymmetrical dimethylhydrazine wastewater, not only because of the hydrophobic environment inside the three-dimensional graphene and the huge specific surface area, there is a very large adsorption capacity, more importantly, it can be combined with metal ions Composite, the synergistic effect of the two can be brought into play, and at the same time of adsorption, it can also catalyze and decompose unsymmetrical dimethylhydrazine under light conditions, so that the purpose of completely eliminating its pollution can be achieved.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a copper-based three-dimensional graphene material and a method for using the same to treat unsymmetrical dimethyl hydrazine waste water. Background technique [0002] Unsymmetrical dimethyl hydrazine is a colorless, flammable, volatile, explosive, and toxic liquid, which belongs to the third-level medium toxicity. As a fuel for liquid rocket engines, UDMH is widely used in the launch tests of spacecraft such as satellites and spacecraft. Although the choice of rocket propellants in the future will develop towards a more environmentally friendly trend (such as liquid hydrogen and kerosene), due to immature technology, Unsymmetrical dimethyl hydrazine / nitrous tetroxide will still perform launch missions for quite some time. In the process of spacecraft launch, engine test run, tank car, storage tank cleaning, etc., a large amount of unsymmetrical dimethyl hydrazine wastewater...
