Abstract
The paper deals with the heavy metals removal by wooden material. The adsorption experiments were carried out using of wood sawdust and bark from poplar tree for the removal of copper and zinc cations from model solutions with initial concentration of 10 mg.L-1. The FTIR was used for functional groups determination not for analysis of hemicelluloses, cellulose and lignin in structure of wood sawdust and bark were studied by infrared spectrometry. Poplar sawdust efficiency for Cu(II) and Zn(II) removal from aquatic model solutions reached approximately 80.0%. Changes of pH values were also observed in model solutions that were probably caused by ion exchange between the ions of sorbents and the ions in solutions.
