DETERMINATION OF THE ADSORPTION AND PHYSICOCHEMICAL PROPERTIES OF ACTIVATED CARBON DERIVED FROM PEACH PITS.
Keywords:
Activated carbon, peach pits, adsorption capacity, physicochemical properties, MDEA purification, surface area, SEM analysis.Abstract
This study investigates the adsorption efficiency and physicochemical properties of activated carbon synthesized from peach pit shells (ShFK) through pyrolysis and steam activation at 850°C. The surface area, pore volume, iodine number, and benzene adsorption capacity of the prepared carbon were comprehensively analyzed and compared with those of the industrially known AG-3 grade activated carbon. Experimental data indicate that ShFK activated carbon exhibits a high adsorption capacity (up to 1.85 g/100 g for benzene), low ash content, and significant surface functionality, including –OH, –CHO, and –COOH groups, confirmed via IR and SEM analyses.
