摘要: 以水和丙三醇(GL)的混合溶液为溶剂，以L-天冬氨酸(L-Asp)为结构导向剂，采用溶剂热法可控制备了由纳米棒自组装而成的空心CeVO4微球。BET结果表明，由纳米棒组装而成的CeVO4空心微球的比表面积高达57.16 m2/g。该CeVO4空心微球对Pb2+的吸附性能优越，吸附过程属于化学吸附，经Langmuir拟合，其理论最大吸附量可达343.6 mg/g。因此CeVO4空心微球在重金属废水处理方面有潜在的应用价值。
Abstract: Employing mixed solution of water and glycerol (GL) as solvent, self-assembled hollow CeVO4 microspheres were prepared by solvothermal method with L-aspartic acid (L-Asp) as structure directing agent. The results showed that the specific surface area of CeVO4 hollow microspheres assembled from nanorods was as high as 57.16 m2/g. CeVO4 hollow microspheres assembled by nanorods have excellent adsorption performance for Pb2+. The adsorption process belongs to chemical adsorption. By Langmuir fitting, the theoretical maximum adsorption capacity can reach 343.6 mg/g. Therefore, CeVO4 hollow microspheres have potential application value in heavy metal waste- water treatment.
