Fabrication of Trimetallic Metal–Organic Frameworks for the Rapid Removal of Bisphenol A from Water

Metal-organic frameworks (MOFs) have attracted widespread attention owing to their promising applications in sample pretreatment. However, trimetallic MOFs remain a challenge to synthesis because generally require multistep synthesis, high energy-cost. Here, a facile ambient temperature synthesis of trimetallic NiCoFe-MOF nanostructures was reported, and then heat treated in nitrogen atmosphere to prepare NiCo/Fe3O4-MOF, which exhibit abundant active sites without destroy the nanostructure. Bisphenol A (BPA) is the most studied compound among the bisphenol group. Many countries have banned the use of BPA because of its toxic effect, which cause many adverse health effects in humans. Therefore, it is important to develop fast identification methods for the removing of BPA in the environment. The material had good removal efficiency on BPA in water environment with the removal efficiency of 88 ± 1.9% within 2 min, and the maximum adsorption capacity reached 53.92 ± 1.27 mg/g.
