Beschreibung
Zusammenfassung:	The invention discloses a preparation method of a CuMn-LDH composite material and a technology for applying the CuMn-LDH composite material to catalytic degradation of azo dyes such as methyl orange (MO), and belongs to the technical field of environmental functional material preparation and organic matter pollution treatment. The invention aims to provide a preparation method of a CuMn-LDH composite material and application of the CuMn-LDH composite material. According to the method, the CuMn-LDH composite material with the efficient removal capacity on the azo dye in the water body is obtained by taking copper nitrate (Cu (NO3) 2) and manganous nitrate (Mn (NO3) 2) as a mixed metal solution and sodium hydroxide (NaOH) and sodium carbonate (NaCO3) as alkaline solutions and adopting a coprecipitation method. The phase, the structure, the composition and the morphological characteristics of the material are represented, and the material is applied to adsorption treatment of high-concentration dye wastewater in
