Abstract (EN): Some persistent pesticides, as organochlorines, are not efficiently removed from usual wastewater treatment plants, unless a tertiary treatment, commonly activated carbon adsorption, is applied. The downside of this practice rests on its high regeneration costs. This fact motivated the research for alternative processes involving the use of natural materials. Pine bark was used in this work, to remove lindane from contaminated waters. The adsorptive capabilities of this material were studied (equilibrium time, adsorption model and saturation of the adsorbent) and the interference of some metals (iron, cadmium, copper, nickel and lead) was also investigated. Results showed an excellent efficiency of adsorption (average 80,65%) and that the presence of the studied metals did not affect both efficiency and the model of the adsorption, within the range of the concentration of the pesticide studied.
