abstract = "Nowadays, various types of inexpensive, sustainable and renewable lignocellulosic waste materials are
increasingly being utilized as precursors for carbon adsorbents production. The usage of the lignocellulosic
wastes for production of carbon materials is very attractive from the point of decreasing waste disposal costs
and improving environment protection through the waste recycling and producing useful products. In this work,
carbon adsorbents were obtained starting from beech sawdust (a waste from the wood industry), and using
hydrothermal carbonization, followed by activation in the presence of KOH as an activating agent. By varying
the activation parameters, activated hydrothermal carbon (AcHTC) samples with different characteristics were
obtained. The specific surface area of AcHTC samples was examined by N2 adsorption, while the nature and
thermal stability of the surface oxygen groups was investigated by Fourier transform infrared spectroscopy and
temperature programmed desorption method. The possibility of using AcHTC samples as adsorbents was
tested using water solution of eleven sterols belonging to the different classes (human/animal and plant
sterols). These sterols, usually present at a very high concentrations in wastewater influent and effluent
samples, can cause numerous endocrine disorders and therefore should be removed from the aquatic
environment. Obtained results showed that activated carbons based on hydrothermally treated sawdust were
highly efficient adsorbents, completely removing all tested sterols from water.",
