Packed Bed Column Studies for the Removal Of Reactive Red Dye Using ECH Cross linked Chitosan Beads
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 12
Abstract
Dyes are coloured substances that have an affinity to the substrates on which they are applied. The dye is generally applied in an aqueous solution, and requires a mordant to improve the fastness of the dye on the fiber.Reactive dyes are a class of highly coloured organic substances, primarily used for tinting textiles. They attach themselves to their substrates by a chemical reaction that forms a covalent bond between the molecule of dye and that of the fibre Bio-adsorbent chitosan has shown very promising characteristics in this field. A comparative study of adsorption of aqueous Reactive red dye solution on noncross linked chitosan beads and ECH cross linked chitosan beads was conducted using fixed bed continuous column. Cross linked beads were found to be more efficient than normal beads. ECH cross linked chitosan beads are visibly more rigid than chitosan beads and they have high stability in acidic medium compared to chitosan beads which disintegrate in acidic medium. Continuous operation of fixed bed with ECH cross linked chitosan beads shows good promise with an efficiency of 60.635% for a bed height of 2.5cm and flow rate of 4ml/min Data from column studies were fitted to three well established column models, Thomas 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 Reactive Red.
