Silica-based aerogels as adsorbents for phenol-derivative compounds

Abstract: h i g h l i g h t s • Highly porous silica-based aerogels with tailored degrees of hydrophobicity. • Adsorbents with promising removal capacity for several phenol-derivatives. • Pseudo-second order kinetics and Langmuir form isotherm for adsorption of SDBS. • Important role of the hydrophobic interactions in the adsorption process.

“…These easy-to-prepare and reusable materials expect to be the promising for the treatment of aqueous solutions not only from benzene but also from its derivatives. For the last years, it was shown high adsorption efficiency of β-CD-containing adsorbents in the absorption of different aromatic compounds from water [14, 18, 2426, 29, 35, 36, 45, 46]. Nowadays, there is an increasing interest in the research and development of adsorbent with satisfying adsorption capacity, high mechanical strength, high reusability, and ready availability, especially the adsorbent based on natural products for their ready availability and excellent biocompatibility, which will not cause additional environmental pollution in their application [26, 45, 46].…”

“…The surface properties including surface areas and surface functional groups of aerogels can affect their adsorption capacity, and a larger specic surface area is benecial to enhance adsorption capacity of adsorbents. 18,19 In this work, we combined the advantages of aluminum and silicon aerogels with a large surface area, and successfully prepared hexamethyldisilazane (HMDS)-modied Al 2 O 3 aerogel (Al HMD ) and SiO 2 aerogel (Si HMD ) by an organic solvent exchange method. Adsorption capacities of the aerogels with different properties for the anionic dye acid orange 7 (AO) have been compared.…”

“…Chlorophenols are important industrial and chemical raw materials widely used in the plastics, cosmetics, polymers, paints/dyes, pharmaceutical and pesticide industries. [1][2][3][4] They are slightly acidic, appreciably soluble in water, and highly toxic to animals and human beings even at very low concentrations, and thus are considered one of the most major pollutants in wastewaters. 5 Such wastewaters that contain chlorophenols are of increasing concern and represent a great potential hazard to both the environment and human health.…”

“…Furthermore, the presence of chlorophenols in wastewaters can increase the susceptibility of a biological system to becoming disturbed. [1][2][3][4][5] Hence, chlorophenols or phenolic compounds must be removed from wastewater before it is discharged into receiving water bodies or the environment.…”
