The aim of the research was to compare the effectiveness of sorption of pollutants from landfill leachate on two granulated activated carbons (AG and BA-10) and biochar (BC). The sorption process of wastewater components on activated carbons was carried out under static conditions for 72 hours. The doses of adsorbents used varied from 2–8 g·dm-3. Results of removing of COD were estimated on the base of adsorption capacity and COD removal efficiency. After 72 h of the process at the highest doses (8 g·dm-3), the COD removal rate ranged from 40% (BA-10) to 60% (AG). In the case of biochar, the COD adsorption rate was 53% The state of sorption equilibrium takes a similar character for BC and AG and is determined after 4 h. The degree of sorption of selected metals from landfill leachate using the analyzed range ranged from 84% to 96% depending on its type.
