Abstract
Dyeing wastewaters present high hazards for the environment and human health. Advanced dye removal may be achieved by magnetic metal–organic frameworks (MMOFs) due to their high adsorption and catalyst efficiencies. However, the existing synthesis strategies of frameworks are often cumbersome and time-consuming in the presence of toxic solvents. Hence, a simple and environmentally-friendly synthetic method is desired. Here, a kind of MMOF, Fe3O4/Cu3(BTC)2 (BTC = 1,3,5-benzenetricarboxylate), was synthesized via a novel aqueous solution-phase synthesis. The product Fe3O4/Cu3(BTC)2 has a high specific surface area of 755.15 m2 g−1, and excellent magnetic performance of 31.2 emu g−1. The Fe3O4/Cu3(BTC)2 can effectively remove methylene blue from wastewater in the presence of H2O2. After having been finished the dye removal, it was easily separated and recycled several times by use of the magnetic technology.
