Biosorption is a biocompatible and environment friendly approach for removal of synthetic dyes from industrial effluent. In the present study, dried biomass of Aspergillus versicolor was used as an adsorbent for the removal of basic dye Methylene Blue (MB) from its aqueous solution. The optimum pH and temperature for adsorption was found to be 7.0 and 28° C respectively. Scanning electron microscopy (SEM) of the biomass suggested changes in surface topology following MB adsorption, while FTIR studies indicated chemical interaction between the surfaces of the biomass with MB. Kinetics study suggested the adsorption rate was fast initially and reached equilibrium at 4 h following a pseudo-second-order-kinetics. The adsorption isotherm follows Freundlich isotherm model. Our data suggests the dried biomass of A. versicolor can be used as a potent bio-compatible adsorbent for the removal of MB.
