Abstract
Textile wastewater effluents yield tons of dyes that, even at low concentrations, are toxic and need to be removed before this water is disposed of in aquatic life. Methylene blue has a low degradation rate and causes severe harm to the environment even at low concentrations. Adsorption is an effective method of getting rid of these dyes. In this study sugarcane bagasse pulp, which is a waste resulting from the sugar extraction process, is examined as an adsorbent for the removal of methylene blue from textile wastewater. Batch experiments are carried out to determine the efficiency of the adsorption of methylene blue onto the sugarcane bagasse pulp surface. Seven different parameters including the adsorbent dose, temperature, initial dye concentration, contact time, pH, and adsorbent particle size are studied to determine their effect on the adsorption process; characterization of the adsorbent is carried out. Artificial neural network is used to determine the optimum conditions that give maximum efficiency. The results of this study showed that bagasse pulp is an effective adsorbent material for methylene blue removal with a maximum adsorption efficiency of 95%.Graphical abstract
