The possibility of obtaining sorbents with a good sorption capacity from miscanthus has been investigated. The chars and the activation products were obtained from the miscanthus in a rotary furnace. The activation process of miscanthus was carried out by water vapour at 700-800°C and at the activation time of 30-90 min. We found that the optimum conditions for the activation process were: the activation temperature of 750°C (activation time of 60 and 90 min) and 800°C (activation time of 45 or 60 min). For these conditions the sorbents with the best sorption capacity for p-chlorophenol, toluene, methylene blue and Congo red were obtained.
