Abstract: Algal Biomass procured from carbon sequestration plant of NALCO at Angul, India, was evaluated for its possible application as an industrial adsorbent. The algal biomass (AB) and carbonized algal biomass (CAB) were taken for the adsorption characteristics. A comparative study of adsorption capacity with commercial activated charcoal (CAC) has been reported in the present work. X-Ray Diffraction and FTIR study were carried for the structural analysis. The BET method was carried out for surface area analysis of the samples. The removal of Methylene Blue (MB) dye has been studied for all the samples and it is observed that the maximum dye removal (98%) occurs with activated carbonized algal biomass. Color reduction potential of the adsorbents was studied on wastewater effluent from paper mill, beverages and steel industries. A maximum of 85.7% of color removal was noted from paper mill effluent that was higher comparable to that with commercial activated charcoal.
