Low Cost Activated Carbon Synthesis, Characterization and Adsorption Applications

Abstract

In this study, activated carbon was synthesis from peach kernel shells, which is agricultural waste. The synthesized activated carbons were characterized and their adsorption properties were examined. Activated carbons were synthesized by the physical activation method and CO2 was used as the activation gas. The synthesis was carried out in two steps. In the first step, it was subjected to the carbonization process at 4 different temperatures. During the carbonization process, two different gas flows were used. In the activation process, a temperature of 800°C was used. The surface area and morphological properties of the obtained activated carbons were studied by BET, XRD, FTIR and elemental analyzes. Methylene blue was used during adsorption. The adsorption capacities of the samples were calculated.
