Abstract

In this study, activated carbon was produced by hydrothermal method from almond shells. In the studies, two different techniques were applied. In the first technique, almond shells were processed directly on the hydrothermal device at different times and temperatures without the use of activators. In the second technique, an activator was used after hydrothermal treatment and activated carbon was produced. Characterization of the obtained products was carried out by BET, SEM and EDX analyses. The surface areas of the products obtained from experiments were measured by BET analysis which is an analytical technique utilized for determining specific surface areas and pore size distributions of solid materials. The surface area of the product generated without the use of an activator was measured at 0.95 m2/g, whereas the surface area of the product created with the use of an activator was measured at 423.56 m2/g, according to the results of the BET analysis. In a 300 mg/L methylene blue solution, the adsorption efficiency was observed to be 76.37%.
