Abstract

This study presents the preparation of magnetic biocarbon from coconut shell. The physicochemical properties of the prepared biocarbon was initially characterized by their iodine adsorptive capacity to estimate structure porosity and surface area. The comparative study was conducted between coconut shell-derived biocarbon (CSB), coconut shell-derived activated biocarbon (CSAB), and magnetic coconut shell-derived biocarbon (MCSB) to evaluate their adsorption efficiency towards methylene blue (MB) dyes in aqueous solution. The iodine number for CSAB showed greater difference compared to the CSB and MCSB. Meanwhile, the adsorption studies indicated that MCSB had higher adsorption value (68.83 mg/g) for methylene blue dye than the other biosorbents. This was due to abundant of Fe3O4 species and oxygen containing functional groups after the biocarbon was modified. The data of MB adsorption by MCSB reflected better adsorption efficiency overall. Hence, magnetization is suggested as a better option for biocarbon modification.
