Abstract/Summary Radiata bark pine has arisen as one of the possible heavy metals extracting agent from aqueous solutions. This innocuous treatment pathway, example of the so-called clean technology, has been studied for numerous authors nevertheless some issues, like global mechanism, are still not well described. This work is devoted to determine the effect of initial-normal heavy metal content present in radiata bark pine over its own ion extraction capability. Separate batch experiences at different conditions of both Cu(II) and Pb(II) adsorption were performed. Many authors have demonstrated that pulp density affect largely the bark pine extraction capability. In equilibrium conditions, the solid/liquid ratio itself defines the adsorption capacity independently of both heavy metal concentration and bark surface state. FTIR, PIXE and SEM analysis corroborated these facts and also proved the existence of different adsorption energy sites. Further kinetic analysis was performed to understand the different adsorption behavior of Cu(II) and Pb(II).
