The study investigated the application of char activated with CO2 and impregnated with amines solutions for removal of selected xenobiotics from aqueous solutions. The chars produced from the pyrolysis of waste tires. The solutions of monoethanolamine (MEA), diethanolamine (DEA) and polyethylenimine (PEI) were used for impregnation of char. The sorption capacity of char impregnated with amines depended on amines chemical properties. The adsorptive removal of mixture of pharmaceuticals residues by modified materials was assessed. BET surface area of materials varied from 36 m2 g−1 to 128 m2 g−1. The highest removal efficiencies up to 99 % were observed for char impregnated with PEI.
