Facile Sonochemical Synthesis of Flexible Fe-Based Metal-Organic Frameworks and Their Efficient Removal of Organic Contaminants from Aqueous Solutions.


ABSTRACT: An iron-based metal-organic framework, MIL-53(Fe), was synthesized via the simple sonochemical method, which is a facial and fast strategy, and their adsorption performance for organic contaminants removal from aqueous solutions was studied. The crystal structure and morphology analysis indicate that the sonochemical synthesis of MIL-53(Fe) particles was faster than the solvothermal preparation method, showing high crystallinity with a downsized hexagonal bipyramid shape. Furthermore, the prepared MIL-53(Fe) exhibited enhanced adsorption capability for the organic dyes compared to metal-organic framework prepared via the solvothermal method and showed excellent maximum adsorption capability for the methyl orange removal from aqueous solutions. Based on the superior adsorption properties and facile synthesis, MIL-53(Fe) prepared by ultrasound irradiation has a potential application for an efficient, economic, and ecofriendly wastewater purification process.
