Methylene Blue Dye Removal Utilizing Green Waste-Banana Stem Based Biomass

Abstract Industrial dyes are used extensively for manufacturing of textile, painting, paper, food and leather etc. The existence of those artificial dyes creates negative impact to the aquatic organisms and human beings when release without treating to the ecosystem. The dyes comprise of toxic and multi faceted elements. Relating to the amount and its detrimental effects, it is essential to create efforts to decrease harmful dye concentration prior to discharge to the water bodies. Farming leftover has been exploring its adsorption capabilities to remove dyes from textile wastewater. In this work, banana stem activated carbon as adsorbent was investigated for methylene blue dye removal and its efficiency was analyzed. The adsorption was examined by changing several constraints for example; pH of dye solutions, activated carbon doses, dye concentration etc.
