Abstract

In this work the results of the biosorption of Pb(II) and Cd (II) of synthetic waters with cocoa shell in fixed bed columns are presented. The experimental data were fitted to several models describing the breakdown curve for single component and two component systems. The removal percentages of lead and cadmium in single-component systems are 91% and 90%, respectively. In bicomponent systems Pb-Cd the percentage of lead removal 88% and cadmium 90%. The Dose-Response model in two-component and single-component systems was the one that best reproduced the experimental rupture curves throughout the measured range.
