In this study, low cost locally available prawn waste was studied for its potential use as an adsorbent for removal of a cationic dye (MB) from aqueous solution. Factors affecting adsorption, such as initial dye concentration, pH, contact time and adsorbent dose, were evaluated. The equilibrium of adsorption was modeled by using the Langmuir, Freundlich and Dubinin-Radushkevich isotherms models. The kinetic parameters and intraparticle diffusion were determined for the MB-prawn waste system. Results of this study will be useful for future scale up using this prawn .
