Description
Summary:The potential of pineapple peel as a biosorbent for a heavy metal, Pb(II), was investigated. The experiment was carried out at various contact times, doses of adsorbent, and pH of the solution. Results obviously showed that pineapple peel biosorbent has potential for removing Pb(II) ions from aqueous solutions. The adsorption of Pb(II) ions depended on the pH of the solution. No significant difference was observed when the adsorption was performed at pH of 4.0 and 5.0. The scanning electron microscope (SEM) evaluation indicated that the surface of pineapple peel (PP) biosorbent is arranged like flakes and fractures, in addition some pores are also present. The biosorbent made from pineapple peel showed a cloud-like layer in the SEM image after adsorption, showing that the Pb(II) ions were successfully adsorbed. About >90% of 100 ppm Pb(II) ions were adsorbed within 5 minutes, indicating that the biosorbent derived from pineapple peel has a fast adsorption capacity. In conclusion, our investigation clearly showed the potential of biosorbent-derived pineapple peel to remove heavy metals, including Pb(II) ions, from solutions.
