In this work, economic, natural, and eco-friendly biosorbent want to be advised instead of traditional methods. For that reason, banana peel-based biosorbents were been done to remove Cu2+, Ni2+, and Co2+ ions from the solution by batch method. Moreover, how their natural assets like density, water intake, solubility, and heavy metal extraction performance were affected by their starch and oil contents had been determined. Flame atomic absorption spectroscopy (FAAS) having been using for the analysis of biosorbents uprooting performance. The density of the biosorbents had worked according to ASTM D 792 standards. As a result, the untreated banana peel-based biosorbents had transported 4.87 mg of Co2+ ions, 4.73 mg of Ni2+ ions, and 4.29 mg of Cu2+ ions from 25 ml 7 ppm of each heavy metal ions solution with 175 rpm agitation speed at 24 °C during half-hour.
