Heavy metal contamination, such as copper (Cu) pollution in aquatic environments, poses serious threats to the environment and human health. This study aims to develop an environmentally friendly adsorbent based on chitosan extracted from crab shells and activated carbon derived from corncob waste. The chitosan preparation process involved deproteinization, demineralization, and deacetylation steps, resulting in chitosan with a high degree of deacetylation of 76%. FTIR analysis revealed the presence of hydroxyl (–OH) and amine (–NH₂) functional groups, which are effective for metal ion adsorption. Activated carbon from corncobs was produced through carbonization followed by activation, leading to increased surface area and material porosity. Atomic Absorption Spectroscopy (AAS) tests demonstrated an adsorption efficiency of 60.26% for Cu ions from Tallo River water, South Sulawesi. These results indicate that the chitosan–activated carbon composite is effective, cost-efficient, and environmentally sustainable for mitigating heavy metal pollution in aquatic environments. Therefore, this composite shows strong potential for application in industrial wastewater treatment and the remediation of contaminated water bodies.
