Applications Chitin and Chitosan-Based Adsorbents for the Removal of Natural Dyes from Wastewater

Sapna Raghav1, Ritu Painuli, Dinesh Kumar

Adsorption is one of the most advantageous techniques for the removal of pollutants. It is fast, simple, cheap with many opportunities to modify the initial materials after appropriate synthesis routes, etc. Numerous adsorbent materials have been prepared in the last years, having as ultimate scope to remove some pollutants especially from contaminated waters (effluents originated from industries). But the composition of each type of effluents is varying. Dyes are some major components of industrial wastewaters. Chitosan and its derivative have received considerable attention in wastewater treatment for dye removal. This chapter highlights the dye removal affinity of Chitosan and its cross-linked and grafted derivatives.
