What is Preparation and Application of Chitosan-Based Membrane: Focusing on Dye Removal about?

Water pollution is caused by the direct discharge of harmful dyes into the environment and is a major global problem. Dyes if present in the water can be toxic to the aquatic organisms and humans. Dyes are recalcitrant in nature, and they can resist attack by heat, light, and microorganisms. Hence, most of the reactive dyes are non-biodegradable and their removal from the aqueous solution is very difficult, and therefore, a necessary measure must be applied in order to tackle the existence of the water pollution problem. Adsorption is a well-known technology that is adopted in the academia and industries for removal of dyes from solution. The adsorption of dyes on adsorbents is a simple and economical procedure that is widely used for large and small-scale removal of dyes. In the current chapter, we reviewed the extraction of chitin from the shells of marine animals, the preparation of chitosan by deacetylation reaction, structure and properties of the chitosan biopolymer. Chitosan films could be prepared by casting technology via dissolution of chitosan in a suitable solvent followed by simple evaporation technique. The chapter highlights that chitosan films have superior physicoc
