ABSTRACT
The aim of this article is a study of the heavy metals removal by wooden material. The adsorption experiments were carried out using wood sawdust and bark from poplar, cherry, and spruce trees for the removal of Cu(II) and Zn(II) from the model solutions with initial concentration of 10 mg.L−1. The FT-IR spectra of wooden materials confirmed the presence of functional groups that have potential for heavy metal binding from the model solutions. The poplar wooden sawdust had the best efficiency of approximately 80.0% for Cu(II) and Zn(II) removal from the model solutions. The changes of the pH values after the adsorption experiments were also measured.
