Abstract

This research aimed to check heavy metal removal using waste biomass adsorbent, banana leaves, in an aqueous solution. Therefore, this research successfully removes a different concentration of heavy elements, including Al, Fe, Pb, and Cd, in an aqueous solution using dried banana leaves adsorbents. The order of removal performance was found to be Fe >Pb > Cd>Al. Different factors are studied, such as the amount of banana adsorbents, contact time, temperature, and pH. The results are compared with removing heavy elements of banana leaves nano adsorbents, where an amount of banana adsorbents is converted to nano one using a Ball mill of banana leaves converted to nanopowder of 40 nm size. It is found that the removal of Pb and Cd from aqueous solutions of the nano banana leaves is more functional than normal banana leaves. Normal banana leaves powder was applied to two samples; the first was a sewage water sample, and the other was ground water. This experiment, in which heavy metals are removed using the waste biomass of banana leaves, is an eco-friendly bio-adsorbent method because it can remove heavy metals without using chemicals
