Abstract In this paper, wheat straw and rapeseed residues before and after microwave pyrolysis during biooil production were studied as potential sorbents of heavy metals. The sorbents were characterized by elemental analysis and FTIR spectroscopy. Sorption properties of the materials were investigated using batch adsorption-equilibrium experiments and the effect of initial Cd and Pb concentration was studied. The experimental data fit Langmuir adsorption isotherm. The maximum sorption affinity of studied materials was observed in the case of rapeseed and its sorption capacity was 31.6 and 83.5 mg/g for Cd and Pb, respectively.
