Technology Development of Adsorption Cigarette Smoke using Modified Activated Carbon with MgO from Waste Biomass of Durian Shell

摘要

Activated carbon is one solution to overcome the problem of cigarette smoke which is very dangerous for health where durian shell waste is chosen as the base material. Durian shell waste was chosen because it contains high cellulose, lignin, and starch, also its production reaching 746,805 thousand tons per year. Durian shell waste that had been activated by chemical activation with K2CO3 versus activated carbon is 1:1, 3:2, and 2:1, and by physical activation with N2 then then was modified with MgO with variations in the concentration of MgO 0.5%, 1%, and 2% at 450oC for 30 minutes. Activated carbon as a result of activation and modified activated carbon were then characterized by the Iod Number test, BET test, SEM test, and EDX test. The best non modified activated carbon was activated carbon chemical-physical 3:2 with results of 41.56% in yield, 399.44 mg/g in iodine numbers, and 694.13 m2/g in surface area. While the best modified activated carbon was 3: 2 2% with a yield of 97%, an iodine number of 625.70 mg/g, and a surface area of ??1,029.90 m2/g. In the CO gas adsorption application, which is the component with the largest contribution in cigarette smoke, and cigarette smoke itself was tested using modified activated carbon. The results obtained that 2% modified activated carbon proved that it was the best type of activated carbon to degrade CO in 3.89%/gram per minute with adsorption ability was 0.215%. This activated carbon was also able to purify the air from the cigarette in 8.04%/ gram per minute with adsorption ability was 0.87%.
