“…These methods include chemical and electrochemical oxidation [6,7], microbiology treatment [8,9], ion-exchange and membrane separation [10], coagulation [11], foam separation [12], and various adsorption techniques [13][14][15]. The adsorptive methods appear to provide the required efficiency for water purification and have advantages when it comes to practical implementation due to, for example, a comparably low cost.…”

A B S T R A C TThe anionic surfactant sodium dodecyl sulfate (SDS or NaDS) was adsorbed from aqueous solutions onto four different sizes of activated carbons (ACs). The concentrations of anionic surfactant in aqueous solutions were determined by UV spectroscopy. In this work, anionic surfactant had a linear dependence of UV absorbance on the surfactant concentration at 200 nm. Changes in the textural properties of the AC after adsorption of surfactants will be studied by adsorption and mercury intrusion porosimetry, and could be correlated to surface characteristics and adsorptive capacity. The mechanism of adsorption was found to be simple. At low surfactant concentrations, adsorption occurred in micropores. We concluded that this surfactant is adsorbed as individual molecules. Adsorption from more concentrated solutions probably occurs in meso and macropores, and resembles surfactant adsorption on flat carbon surfaces. ACs with small pores appears to be most effective for surfactant removal. Controlling the pore size distribution of the ACs would be beneficial in the application of ACs for removal of surfactants from wastewater.

“…Adsorption is a convenient, efficient, environmentally friendly, easy of operation and cost-effective process. [15][16][17][18] Different adsorbents such as chitosan, [19] fly ash-based geopolymer, [6] silica, [20] zero-valent iron nanoparticles, [21] bentonite, [22] cellulosic surface, [23] alumina, [24] zeolites [25] and chromium leather waste [26] were utilized for the adsorption of surfactants from aqueous solutions. Carbon-based adsorbents such as activated carbon, [8,27,28] carbon black, [29,30] multi-wall carbon nanotubes (MWCNTs) [31][32][33] and graphene oxide [34,35] have been suggested for pollutants removal.…”

The objective of the study is to investigate the potential of carbide-derived carbon (CDC) for the adsorptive removal of nonionic t-octylphenoxy poly ethoxy ethanol (TX-100), anionic sodium dodecylbenzene sulfonate (SDBS) and cationic 1-hexadecylpyridinium bromide (HDPB) surfactants from water. The CDC was characterized using TEM, SEM, FTIR, BET, EDS, XPS methods and zeta potential measurements. The effects of adsorption parameters included initial surfactant concentration, contact time, temperature, and pH of the feed solution were evaluated. The adsorption capacity and mechanism were determined by modeling the isotherm, kinetic and thermodynamic data. The kinetics results demonstrated that the adsorption of the surfactant by CDC obeys the pseudo 2 nd order model. The thermodynamic results have shown that surfactants adsorption by CDC is an endothermic and spontaneous process. The Sips model agreed with the adsorption isotherm data of SDBS with R 2 of 0.987, while both Freundlich and Redlich-Peterson models comply well with adsorption data for TX-100 and HDPB. The hydrophobic and electrostatic interactions were found the dominant mechanisms of the adsorption of the surfactant by CDC. The adsorption capacities of CDC were found to be 442.4, 462.0 and 578.4 mg/g for SDBS, HDPB and TX-100, respectively.

“…They consist of a hydrophobic part, which is usually a hydrocarbon backbone, and a polar, hydrophilic part, known as the head group, which may also be charged. The most significant property of surfactants is the ability to adsorb at interfaces, [1][2][3][4][5][6][7][8][9][10][11] which can dramatically change the properties of the interface. The adsorption pathway and associated dynamics are very important, and the structures of the adsorbed layers can change significantly with time.…”
