Composites Based on Cellulose and Metal-Organic Frameworks for Removing Dye from Wastewater

Industrial wastewaters from enterprises using dyes are one of the main contaminants of the environment and surface waters. In recent years, much attention has been paid to innovative ways of removing this problem. This work reviews research over the recent decade on different ways of removing biological, chemical, and physical dyes and evaluates their efficiency. The possibility of using cellulose and cellulose based materials in the removing dye from aqueous solutions is shown. Special emphasis is placed on the composites based on cellulose and metal-organic frameworks (Cell-MOFs). Main approaches to creating Cell-MOF materials and the possibilities of controlling their properties are considered. Examples of using Cell-MOF materials to remove dye from aqueous solutions via adsorption and catalytic methods are given. Problems and prospects of applying them in practice are discussed.
