Valorization of Agricultural Waste into Value Added Products for the Removal of Industrially Important Dye towards Environmental Sustainability

This study explores preparation (thermally) and activation (chemically) activated carbon from Areca spathe (AS)for the removal of Amido black 10B (AB10B) dye by batch adsorption method. The surface characteristics of the ASC was analyzed using SEM and FTIR. Adsorption ability of ASC to remove AB10B has been investigated by varying various experimental parameters such as initial concentration, contact time, dose and pH of the dye solution. Acidic pH was more favorable for AB10B adsorption and the equilibrium adsorption data was well described by the Langmuir model with adsorption capacity of 123.0 mgg−1 for ASC and 148.08mgg−1 for CAC. The adsorption kinetics was found to be best represented by the pseudo-second-order kinetic model. As a result, the optimum ASC can serve as cost effective and efficient adsorbent for removing dyes from industrial wastewater.
