Abstract:Cocoa shell is a potential adsorbent for the removal of pollutants from wastewater. The goal of this study was to compare, model and simulate the removal of Pb2+ and Cd2+ in a fixed bed column using cocoa shell. The experimental studies were carried out in a laboratory burette with a bed height of 10.5 cm, a volumetric flow of 2 mL/min, and a metal concentration of 10 mg/L. The empirical models of Thomas, Dose-Response, and Wang were used to study the dynamic behavior of biosorption, in addition a mathematical… Show more
