Physicochemical Characterization of a Local Biomaterial and Its Applications in Adsorption

Abstract

The main objective of this work is to study the adsorption phenomenon of Congo Red pollutant from wastewater using a local natural adsorbent which is palm leaves. Dye removal by palm leaves is studied by varying the influencing factors such as adsorbent mass, contact time, initial concentration, pH and temperature, the results show that palm leaves are a good adsorbent for this type of pollutant. The kinetic study showed that the pseudo-second-order model is suitable for the adsorption of Congo Red on palm leaves. While the isothermal study showed that the Freundlich model is more suitable compared to other models.
