The application of ferric-metal-organic framework for dye removal: A mini review

Abstract

Dye effluent released from the industries is one of the most severe environmental concerns due to their potential adverse effects on human health. There are many obstacles encountered in degrading dye materials as they are not only very stable to light and heat but also resistant to biodegradation and oxidation reactions. Currently, porous metal-organic frameworks (MOFs), an important class of advanced functional materials due to its novel coordination structures and diverse topologies, have shown potential applications in various fields, including dye removal. Among the highly water stable MOFs, Ferric-based MOFs like iron (III) trimesate, which is also known as MIL-100(Fe), is favorably ascribed by its simple synthesizing method as well as its wide availability. Herein, this paper summarized the recent progress achieved by MIL-100(Fe) in removing different types of dye, together with its sustainable preparation method.
