摘要

The pervasive issue of heavy metal pollution poses significant environmental and health risks, necessitating effective remediation strategies. This literature review critically examines the potential of various parts of the banana plant (Musa spp.)—including leaves, stems, and peels—as absorbents for removing heavy metal contaminants from water and soil. Through an extensive analysis of recent studies, this paper evaluates the adsorption capacities, mechanisms, and efficiency of each banana plant component in sequestering metals such as lead (Pb), cadmium (Cd), and chromium (Cr). Comparative assessments reveal the differential effectiveness of banana leaves, stems, and peels, highlighting the structural and chemical properties contributing to their adsorptive performance. The review concludes with a synthesis of findings, identifying the banana peel as the most effective component for heavy metal adsorption due to its high surface area, porosity, and functional groups conducive to metal binding. Recommendations for future research directions and practical applications in pollution mitigation are also discussed.
