  Rezumat:  This paper presents experimental results obtained in the process of phenol adsorption from synthetic wastewaters in batch conditions using a carbon aerogel (CA) as adsorbent. Influence of the phenol initial concentration and contact type over the process efficiency was studied. The carbon aerogel adsorbent was prepared by polycondensation of resorcinol and formaldehyde followed by drying in supercritical condition with liquid CO2 and a pyrolysis step. Morpho-structural characteristics of carbon aerogel were investigated using transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and specific surface area determination using nitrogen adsorption (BET method). Obtained carbon aerogel proved to be an efficient adsorbent for phenol from wastewaters. Adsorption efficiencies up to 94.32% were reached.

Keywords: carbon aerogel, phenol, adsorption
