The interactions of phenol, aniline and p-nitrophenol, adsorbed from aqueous solutions, with the surface of two activated carbons (with and without oxygen surface groups) were followed by temperature programmed desorption, thermogravimetry and analysis by mass spectrometry. The results reveal that on bare surface the three molecules can be presented as physisorbed and chemisorbed species. When oxygen...
The adsorption behavior of phenol, aniline and phenol–aniline mixtures in water over carbonaceous material surfaces has been studied. The adsorbents used were: a mesoporous high surface area graphite (HSAG) and a microporous activated carbon (AC). Aliquots of AC were treated with HCl and H 2 F 2 to remove inorganic surface impurities. Furthermore, samples of HSAG and AC were subjected...
