Activated Carbon from Biomass from Zncl2 Activation for Methylene Blue Adsorption

Abstract

Investigations were conducted on activated carbons derived from the plentiful natural resource of Zizyphus lotus L seeds for the purpose of eliminating methylene blue from aqueous solutions. These activated carbons were synthesized through chemical activation using zinc chloride under various conditions, aiming to achieve carbons characterized by elevated porosity. An essential parameter influencing the porous structure of the resulting charcoal was the carbonization temperature. Through SEM analysis, the activated carbons were thoroughly characterized, and BET specific surface area analysis was employed to estimate pore volume and surface area. The activated carbons exhibited surface areas (S_BET) and micropore volumes approximately measuring 313.53 m²/g and 0.108519 cm³/g, respectively. Notably, the developed activated carbon displayed a considerable capacity for adsorbing methylene blue from aqueous solutions.
