Removal of dye in aqueous Solution using sugarcane bagasse

The use of sugarcane bagasse, an agro industry waste, to remove methylene blue dye from the wastewater was studied. The percentage removal of dye using untreated sugarcane bagasse were examined at varying concentration of dye, adsorbent dosage and contact time. The interaction between factors and their optimum levels for maximum percentage removal of MB were determined using Response Surface Methodology (RSM) via Box Behnken Design (BBD). It was found that the dye removal was increased with the increment of adsorbent dosage. All the models were highly significant with correlation coefficients (R2) near to unity. 0.93g adsorbent dosage, 26.92ppm dye concentration and 13.47h contact time. This study demonstrates that untreated sugarcane bagasse is an effective and cheap adsorbent for the removal of dyes from the aqueous solutions and the possibility of using it for a simple and inexpensive method for dye removal from waste waters in a batch or stirred tank reactors. The data obtained may be useful for designing an economical and optimized treatment process using batch or stirred tank reactors for the removal of methylene blue from industrial effluents.
