| The study focused on the preparation of activated carbon and the examination of its properties. Activated carbon was produced by soaking Ficus carica L. wood in a sodium hydroxide (NaOH) solution. The mixture of wood and NaOH was then filtered, dried, and thermally carbonized until all vapors and gases were expelled. Soaking the wood in varying concentrations of NaOH for 48 hours resulted in an increased retention of the base within the wood. The findings indicated that Sample 5 (with a base-to-wood ratio of 2:1) exhibited the highest adsorption capacity for Methylene Blue dye, achieving a rate of 298 mg/g. In contrast, Sample 4 (with a base-to-wood ratio of 1.5:1) demonstrated superior iodine adsorption, reaching 853 mg/g. Additionally, other measured parameters such as density, humidity, and ash content were found to be within acceptable limits. |
