The adsorption capacity of the rGOs was fairly high even toward reasonably water‐soluble organic compounds such as rhodamine B (321.7 mg g −1) and aspirin (196.4 mg g −1). Removal of tyrosol from water by adsorption on carbonaceous materials and electrochemical advanced oxidation processes. Adsorption on activated carbon is currently the most frequently used technology to remove organic chlorinated pollutants from wastewaters. Pp. Although activated carbon presents high adsorption capacity, due to its high specific surface area, it is an expensive adsorbent material. In order to explore a new sequential process for water treatment its two steps, adsorption on activated carbon and in situ photocatalytic oxidative regeneration, were investigated successively. Universidad de Granada. The pH of the waste stream. When a solution containing absorbable solute comes into contact with a solid with a highly porous surface structure, liquid–solid intermolecular forces of attraction cause some of the solute molecules from the solution to be concentrated or deposited at the solid surface. L-1). Adsorption of organic compounds by GAC filters is influenced by a number of water characteristics as e.g. In the present work, an overview of the recent research studies dealing with adsorption method for the removal of NOM and related compounds from water is presented. Removal of Organic Compounds from Water via Adsorption Onto Polymethyl-Hydrosiloxane Pentenyl-β-Cyclodextrin. To adsorb phenol selectively from water, adsorbents must be hydrophobic, i.e., zeolites owning a high Si/Al ratio. The higher the concentration, the higher the carbon consumption. Zeolites were used as adsorbents, and adsorption properties were compared to those of an activated carbon. Adsorption is a surface phenomenon with common mechanism for organic and inorganic pollutants removal. Chemosphere 2018, 201 , 807-815. Regarding the adsorption processes, activated carbon is one of the most commonly used adsorbents to remove organic and inorganic pollutants from wastewater. 18071, Granada, Centro de Investigacion … Yet they exhibited salinity‐enhanced adsorption capacity and preferential adsorption of organic compounds with lower solubility in water. Title:Removal of Tetracyclines from Water by Adsorption/Bioadsorption and Advanced Oxidation Processes.A Short Review. The type of compound to be removed. A wide variety of conventional and non-conventional adsorbents have been reviewed for their potential in NOM removal from water. Influence of the Surface Structure of Graphene Oxide on the Adsorption of Aromatic Organic Compounds from Water. Specific organic pollutants (SOPs) such as phenolic compounds, PAHs, organic pesticides, and organic herbicides cause health and environmental problems due to their excessive toxic properties and poor biodegradability. The present study examines the ability of five commercially available types of activated carbon to remove organic chlorinated compounds from the effluent of a chemical plant. Granular activated carbon (GAC) adsorption is a widespread water treatment technology especially applied in waterworks for removing dissolved organic compounds (natural organic matter, micropollutants). Several commercial activated carbons (AC) and sewage sludge based activated carbons (SBAC) were tested with several phenols and one dye as pollutants. The aim of this chapter was to show how the concentration of some organic compounds may be reduced by means of natural zeolites as sorbents. Low-cost biosorbents are considered as a promising alternative for conventional adsorbents to remove SOPs from water. … Compounds with high molecular weight and low solubility are better absorbed. Use of Natural Zeolites for Organic Compounds Removal from Water. VOLUME: 22 ISSUE: 10 Author(s):J. Rivera-Utrilla*, R. Ocampo-Perez, M. Sanchez-Polo, J.J. Lopez-Penalver and C.V. Gomez-Pacheco Affiliation:Departamento de Quimica Inorganica.Facultad de Ciencias. The concentration of the compound to be removed. Journal of Liquid Chromatography: Vol. Abstract.
