Modeling of Fixed Bed Column Studies for Adsorption of Azo Dye on Chitosan Impregnated with a Cationic Surfactant PDFShadeera Rouf, M. NagapadmaRemoval of diazo dye Brilliant Black BN from aqueous solution was studied by conducting adsorption in fixed bed column using chitosan beads impregnated with a cationic surfactant Cetyl Trimethyl Ammonium Bromide. Effect of flow rate, bed height and initial dye concentration were investigated. Maximum bed capacity, percentage dye removal and equilibrium dye uptake were determined and break through curves were plotted. Percentage dye removal increased with decrease in flow rate and increase in bed height. Maximum bed capacity of 6.80 mg was obtained at a flow rate of 0.8 ml/min, bed height of 8 cm and initial dye concentration of 100 ppm. Data from column studies were fitted to three well established column models, Thomas model, Adams-Bohart model and Yoon-Nelson model. The experimental data were in good agreement with theoretical results. The study revealed the applicability of chitosan in fixed bed column for removal of azo dyes.
