Removal of Indigo Carmine and Eosin Y Anionic Dyes from Aqueous Solution by Fixed Bed Chitosan

jasem Front Page
Abstract:
The removal of Indigo carmine and Eosin Y from aqueous solutions using natural adsorbent Chitosan in a fixed bed has been investigated. The effect of initial concentration on the breakthrough curve has been examined. The adsorption isotherm of Indigo carmine and Eosin Y from aqueous solution on chitosan in a packed bed at 303.15 K was determined The break through experimental results are tested with Thomas model, Yoon-Nelson model and Adam-Bohart model by means of non-linear regression analysis.

Keywords:Adsorption, Breakthrough Curve, Eosin Y, Fixed Bed, Indigo Carmine.
