Sugarcane bagasse- a low cost adsorbent for removal of methylene blue dye from aqueous Solution


Dyeing effluent is one of the critical environmental problems now a days. The objective of the work was to evaluate a suitable cost conservative adsorbent for methylene blue removal from an aqueous solution. Low cost adsorbents such as sugar cane bagasse, corn corb, paddy straw, rice husk and coconut fibre were taken for color removal. According to efficiency of dye removal, sugar cane bagasse was selected among four low cost materials. Effect of specific adsorption capacity on initial dye solution concentration was studied. Then adsorption equilibrium study was investigated to estimate adsorption parameters using Freundlich and Langmuir's isotherm models with varying dye solution concentration from 100 to 450 ppm. The maximum specific uptake capacity on sugarcane bagasse was found to be 108.67 mg/g.
