Chitosan is the most widespread bio polymer available in nature. Chitosan has economic value because of its biological activities, industrial and biomedical applications. In the present study, Chitosan polymer was obtained by deacetylation of Chitin, It was created by applying on alkaline Chemical like sodium hydroxide to the chitin shells of Shrimp. The chitosan Polymer was characterized by elemental and spectral analysis to confirm its structure. Chitosan based adsorbent has received a lot of attention for adsorption of dyes as the textile anionic Remazol red (RR) dye and malachite green dye from aqueous solution. Chitosan resulted in more efficient removal of (RR) dye (100%) than malachite green at certain condition. The kinetic study results were best fitted by pseudo-Second-order kinetic model.
