ABSTRACT:
Present research discussed the adsorptive elimination of Methyl Orange [MO] by yellow green algae, Vaucheria sp. from synthetic wastewater. The adsorption process was found to be highly dependent on various operative variables, such as the pH of aqueous solution, contact time to reach equilibrium, the dosage of adsorbent, temperature and the chemical pretreatment for dye removal. Adsorption of the dye over the adsorbent has been monitored through Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) isotherms with Langmuir isotherm showing the best-fit. To describe the adsorption mechanism kinetic models such as pseudo-first order, pseudo-second order and intra particle diffusion were applied and pseudo-second order kinetic model was found to adequately describe the kinetic data. Thermodynamic analysis of the adsorption process of MO dye on this yellow green alga confirms their spontaneity and endothermicity. In order to explore various properties of the adsorbent used i.e. Vaucheria sp., surface area was calculated by BET method, surface morphology studies by SEM and functional group studies by FTIR. Thus, this study demonstrated that easily available, Vaucheria sp. could be used as an efficient adsorbent for the treatment of wastewater bearing MO dye.
