摘　　要：综合性实验有助于高素质军事人才综合能力的培养。为了紧贴军事,紧跟前沿,设计了一个采用氧化铜/石墨烯复合材料处理偏二甲肼废水的综合实验。首先以石墨为原料合成出氧化石墨烯,然后以氧化石墨烯和铜盐在水热条件下反应生成氧化铜/石墨烯复合材料,最后利用紫外-可见分光光度计研究其对偏二甲肼的降解性能,根据偏二甲肼的浓度随时间变化的规律,确定该反应的表观反应级数以及表观反应速率常数。该实验涉及传统合成方法、透析分离方法、水热合成方法、仪器分析方法、物理化学实验方法,综合性强,直接面向发射井废水的处理,应用性强,有利于提高军校学员的综合操作能力和应用能力,培养学员的创新能力。Comprehensive experiments are conducive to the cultivation of the comprehensive capabili-ties of high-quality military personnel.In order to keep up with the military and keep up with the fore-front,this article designed a comprehensive experiment using copper oxide/graphene composite materi-als to treat unsymmetrical dimethylhydrazine(UDMH)wastewater.First,graphene oxide was synthe-sized from graphite as a raw material,and then graphene oxide and copper salt were reacted under hy-drothermal conditions to form a copper oxide/graphene composite.Finally,the UV-Vis spectropho-tometer was used to study its catalytic effect on the degradation of UDMH based on the variation of the concentration of UDMH with time,establish a quasi-order kinetic model.The experiment involves tra-ditional synthesis methods,dialysis separation methods,hydrothermal synthesis methods,instrument a-nalysis methods,and physical and chemical experimental methods.It is highly comprehensive and di-rectly faces the treatment of silos wastewater.It has strong applications and is beneficial to improving the comprehensive operational capabilities of military academies.And application abilities,and culti-vate students' innovative abilities.
