Abstract
This article aimed to study the low cost, available and renewable biological adsorbent for the removal of reactive textile dye from aqueous solutions. Batch experiments were carried out for sorption kinetics and isotherms. Operating variables were time and pH. Biosorption capacity seems to be enhanced by decreasing the pH. Maximum color removal was observed at pH 3–5. Experimental sorption kinetic data were fitted to both Lagergren's first-order and pseudo-second-order models and data were found to follow pseudo-second-order for all adsorbents (R 2 = 0.987).
