In the production of banana, shell is generated, and its availability as waste can be exploited in obtaining a natural adsorbent for the removal of heavy metals in water. In this sense, the adsorption capacity of banana peel “musa sapientum“ for the removal of Pb (II) in aqueous solutions was evaluated. The shell was previously dried at 80 °C for 14 hours, passed through grinding and sieved to obtain a particle size fewer than 1 mm. Also, the shell was characterized with moisture content, ashes, reducing sugars, crude fiber and titratable acidity. In the adsorption study, the influence of contact time, pH, adsorbent content and initial lead concentration were evaluated. The contact time with the highest adsorption capacity was 20 minutes. In the case of pH, the highest yield was obtained at pH 4. The evaluation of the adsorbent content showed that the best results were for a content of 5g/L. Finally, about 99% removal was obtained for an initial concentration of Pb (II) of 100 mg/L. According to the results obtained, it was demonstrated that banana peel can be recognized as a potential, environmentally friendly, low cost adsorbent with a yield greater than 80% to remove heavy metals such as Pb (II) from contaminated water.
