Abstract

This research aimed to investigate the effect of carbonization temperature, type, and acid concentration as an activating agent on the physicochemical properties of activated carbon made from banana (Musa acuminata) peels waste. Carbonization was performed at four different temperatures of 200, 300, 400, and 500°C for two hours, while chemical activation was carried out using varying concentrations of hydrochloric and phosphoric acid. During the experiment, carbon was impregnated with HCl and H3PO4 at three varying solution concentrations of 3, 6, and 9 % for 24 hours. Subsequently, sample characterization was conducted using ASTM D2867, ASTM D2866, ASTM D4607, morphology was observed with SEM, the functional group was analyzed using FT-IR, and BET equipment was applied to determine physicochemical properties. Activated carbon was used as an adsorbent to remove ferric ions and iodine (I2) from the solution. The results showed that the product derived from carbonization at 300°C and activation using 9% hydrochloric acid produced the highest adsorption capacity of 1.104 mg/g and 1881.51mg/g for ferric ions and iodine, respectively. Moreover, activated carbon derived from banana peels showed the potential to be regenerated for approximately four times, but with a decrease in efficiency to 75%.
