Recently, water pollution has increased due to various industrial wastewater. Among them, the dyestuff contaminant harms the aquatic environment and human health. Research on wastewater management using activated carbon and biopolymers is being actively conducted to solve this problem. The purpose of this study is to prepare Crustacean-derived activated carbon(AC)/biopolymer composite beads for the removal of ionic dyes and to evaluate the dye adsorption performance. Porous AC of 2000 m2/g or more successfully prepared using chitin as the biocarbon precursor. The prepared AC was effectively introduced into the chitosan network structure and processed a bead-type adsorbent with structural stability. As a result of the dye removal experiment, beads exhibited dye adsorption capacity of AO‑ 503 mg/g and MB+ 529mg/g, respectively. These biomass-derived carbon/polymer composite beads are expected to be applied to various environmental restoration fields in addition to dye adsorption.
