Preparation and characterization of Groundnut shell activated carbon as an efficient adsorbent for the removal of Methylene blue dye from aqueous solution with microbiostatic activity

This study describes about the preparation of low-cost and eco-friendly groundnut shell activated carbon (gsac) by combined physical- and chemical-activation in a laboratory-scale facility. the fluorescent emission scanning electron microscope analysis exhibited well-defined pore formation and the energy dispersive x-ray analysis showed elemental composition of gsac which is essential for the strong adsorption of the dye molecule. this study significantly emphasizes that gsac would be the effective adsorbent to remove methylene blue dye from aqueous solution that accompanied with significant microbiostatic activity. utilization of groundnut shells serves dual purpose of simultaneous waste eradication,as well as cost-effective pollution treatment process. © 2017,university of mohammed premier oujda morocco.
