摘要

In this study, activated carbons were obtained by carbonizing the waste laurel fruit seeds at 500°C as a result of oil extraction from laurel fruits brought from Hatay (a province in Turkey). At the same time, activated carbon was obtained by impregnating bay fruit seeds with ZnCl2. Through the use of FTIR, BET, SEM, and TGA, the activated carbons were characterized. In order to remove methylene blue from an aqueous solution, activated carbon was used as an adsorbent. ACn and ACz activated carbons with surface areas of 783.58 and 812.25 m2/g were obtained. We looked at how temperature, pH, and starting concentration affected the amount of MB that ACz removed from an aqueous solution as a function of contact time. The kinetics parameters were also calculated. According to kinetic data, Since the R2 value is large and the ARE value is small, the adsorption phenomenon is considered to be pseudo-second order.
