Composites based on cellulose and metal-organic frameworks for dye removal from wastewater

Industrial effluents from enterprises using dyes are among the main production wastes polluting the environment and surface waters. In order to solve this problem, much attention has recently been paid to innovative processes for their removal. The review considers research works over the past 10 years on various biological, chemical and physical methods for dye removal and assesses their effectiveness. The possibility of using cellulose and cellulose-based materials for dye removal from aqueous solutions is shown. The main attention is paid to composites based on cellulose and metal-organic frameworks (Cell-MOF). The main approaches to the creation of Cell-MOF materials and the possibility of regulating their properties are considered. Examples of using Cell-MOF materials for removing dyes from aqueous solutions by adsorption and catalytic methods are given. Prospects and problems of their practical use are discussed.
