| titleOfInvention | Method for preparing CuO-TiO2/zeolite nanocomposite material for treating dye wastewater |
| abstract | The invention belongs to the field of material preparation, and discloses a method for preparing a CuO-TiO2/zeolite nanocomposite material for treating dye wastewater. The method comprises the following steps: firstly pretreating with hydrochloric acid and calcining to obtain natural zeolite; mixing butyl titanate, anhydrous ethanol and diethanolamine according to a ratio of 3:10: 1 to prepare TiO2 sol, dispersing the natural zeolite in the TiO2 sol, heating in a water bath, stirring, drying, and calcining to obtain TiO2/zeolite; and finally preparing a Cu(NO3)2 solution with the concentration of 5mmol/L, uniformly dispersing TiO2/zeolite in the Cu(NO3)2 solution, stirring, drying, and calcining to obtain the CuO-TiO2/zeolite nanocomposite material. Therefore, the obtained CuO-TiO2/zeolite nanocomposite material has dye wastewater treatment efficiency of more than 90% after being measured by a UV-visible spectrophotometer under fluorescent illumination. The prepared CuO-TiO2/zeolite nanocomposite material is easily recycled, is good in adsorption and degradation performances and low in overall cost. |
