Low Cost Biodegradable Adsorbent Material for the Removal of Dissolved Dyes from Aqueous Solutions: An Economical Process

Abstract—The use of low cost, recycled waste and eco-friendly absorbent has been investigated as an alternative process for replacement of currently expensive process for removing dyes from wastewater. In this study, Acid activated saw dust was used to remove dyes from aqueous solution in a column filtration reactor. Saw dust is an excellent low cost adsorbent of colored organic anions and may have significant potential as a color removal from tannery wastewater. The effectiveness of acid activated sawdust in absorbing Lurazol Brown pH (LBP) dye from aqueous solutions was studied as a function of agitation time, adsorbent dosage and initial dye concentration. The experimental data were fitted to Langmuir and Freundlich isotherm and found that adsorption process follows both the isotherm. The values of Langmuir and Freundlich constants indicate favorable and beneficial adsorption. A two-stage treatment system was developed and its performance assessed in relation to a variety of initial dye concentrations. This was backed by a series of laboratory experiments, the results of which provide a better scientific understanding of the biodegradable material like acid activated sawdust and help realize their potential as commercial products.
