Heavy metals adsorption by banana peels micro-powder: Equilibrium modeling by non-linear models
In this study the copper and lead adsorption efficiency onto banana peels powder was investigated. The agro-industrial waste recovery represents one of the Circular Economy pillars. In the view of the synthesis of an environmentally friendly adsorbent material, the powder was used without any preliminary chemical or thermal activation, but only after simple washing, drying and grinding. The bio-adsorbent was characterized by the FTIR technique and tested in batch mode on synthetic aqueous solutions containing Pb and Cu in the range 10–90 mg·L− 1.
