Synthesis of Activated Carbon from Adonidia merrillii Seeds

Abstract

This research paper presents a novel approach to the production of activated carbon (AC) utilizing Adonidia merrillii seeds, a readily available biomass resource. The study outlines the step-by-step process of activation, including preparation, activation, and characterization of the resulting AC. The ACs were prepared by carbonization method which was then followed by activation of carbonized A. merrillii seeds. ZnCl2 was used as the activating agent at an impregnation ratio of 1:10 wt/vol. Physicochemical properties, such as surface area, pore size distribution, and adsorption capacity, were extensively analyzed. From the XRF analysis, the elemental composition of merit of the AC is potassium chloride known as sylvite, 0.435; calcium oxide also known as lime, 2.850; chloroapatite, 2.850; silicon dioxide, also known as quartz, 1.669; and y-anhydrite, 1.405. The X-ray diffraction analysis conducted on the AC showed that sylvite had the highest percentage of 25%, Lime, 22.5%, chloroapatite, 17.3%, quartz, 19.3%, and anhydrite with the least percentage of 15.6%. The results demonstrate the potential of A. merrillii seeds as a sustainable precursor for producing AC with desirable properties for various applications.
