Decolourization potential of microalgal biomass of an unicellular green alga (Chlorella vulgaris) was studied using different concentrations of Orange-G dye. Several parameters were also optimized for better removal of the tested dye from its aqueous solution. Langmuir and Freundlich models were tested for equilibrium studies and experimental data of the present study are better explained by the Freundlich model. FTIR data showed that five functional groups were probably involved in the adsorption of the dye. The biosorption process using algae (including C. vulgaris) offers an excellent biosystem for the remediation of final discharge of textile effluents.
